Regarding the RAM thing, yes your machine is only as fast as the slowest RAM module.

Thanks for the interesting information guys. I think i'll get 8Gb of Ram now. Indigo sounds like a good renderer to try. I like Vray because its is really fast. I've been doing relatively small sized renderings thats why they didn't impact on my Ram noticeably.
Since I am gonna be using Rhino as well I think I'll stick to the Quadro FX Card, however the new GTX 200 series has ludicrous amount of bandwidth! Don't know if anyone has had experience with FireGL cards form ATI?
I heard that in Q3 Intel is due to release several new processors which would mean the Q9550 would most like drop in price. I think its a good processor with good OC headroom. Which brings me to the question. Does anyone have experience with OCed (Overclocked) systems and performance in Sketchup?
-
I havent got any personal experience with overclocking and SU, but on a theoretical level it should work pretty well, as all your doing is increasing the clock speed of the CPU, and as SU cant take advantage of lots of cores, its pretty beneficial to have each one running fast so SU can take advantage of the individual speed.

I just did the city- and the cube-test with my brand new laptop (
)(Intel Core 2 Duo 2.5Ghz, 4GB Ram, Nvidia GeForce 9650 with 512Ram,)
and interestingly I discovered, that the screen resolution does NOT change the framerate at all!
scene7 of the city test took:
216 Secondswith a resolution of 1980 x 1050pixels
and
215 Secondswith a resolution of 800 x 600pixels
can anybody explain to me, why that is? may it be, because all the SketchUp geometry (inclusive of shadows?) is vector-based and therefore doesn't affect the resolution at all? does that mean in reverse mean, that you can run a screen with a resolution as high as you like (that is supported by your graphic card) without losing any framerate?
-
That doesn't make any sense. Surely higher screen resolutions mean more pixels to update for the graphics card!!!
-
That means its probably something the CPU deals with that is slowing SU down, although i cant remeber which bits of the model the cpu deals with
-
Regarding the screen resolution, the same has held true for me as well. I have 2 monitors. One is set to 1600x1200 I think and the other is 1280x1040ish. I ran the test on both and got the same results. I didn't even mention it because I thought maybe I was crazy for assuming their should be a difference.
Conclusion: SU is wierd and defies the laws (sketchy) physics.

I've read this thread with interest but being a computer dunce I have no idea what all these technicalites mean
I want to buy myself a really good computer in the next couple of weeks as I'm hoping to be doing a lot more SU work and rendering in the future and want a machine that is going to keep up with the demand.
Has anyone summarized all this data yet and come up with the definitive spec?
Or could someone advise on the very best computer to get?
I've bought about 4 computers in the past and always end up with ones that are slow
. I don't want to make the same mistake this time around. My bank balance won't allow it. -
If your looking for a beefy render machine you'll want to go for a quad core or more. You'll also want to get as much RAM as you can afford, id suggest about 16 GB. You'll also need a 64 bit operating system to go with this.
The really tricky bit is graphics cards as these are the things that can mess around with SU if you dont go for the right one. I can noyl vouch for the nvidia 7800 as thats what ive got. Its worth checking out this survey to see what everyone else has got and what seems to work for everyone.
Apart form that everything else is pretty much down to how much you want to spend.
this is probably a good starting point: http://www1.euro.dell.com/content/products/productdetails.aspx?c=uk&cs=ukbsdt1&id=precn_t7400&l=en&s=bsd

C'mon, Remus, don't tease me! I quickly put together a not even top machine for the price of 6,223 GBP (VAT not included)
-
A positive bargain! i put together one for 12, 600 GBP
-
Well, I tried to be realistic (to my budget)
-
Yeah, I recently upgraded to a quad core with 8gb memmory, running Vista 64 bit (which is working great for me). I have an nVidia 8600 w/512mb memmory. My system is great. Even though SU doesn't take advantage of quad cores exactly, it still comes in handy. For example, the other night I had some videos to render. I was rendering 2 videos (2048x1536 resolution) out to .png files. And also running a batch operation in photoshop to automatically resize images from other videos I had rendered down to 1024x768. So that was 3 intense operations working just fine together. So I started browsing the web and didnt even notice a hitch in my performace. So I went and played Battlefield 1942 (video game), at highest graphic settings. Not a single hiccup. While rendering 2 videos, and processing a batch of images. I am soooo happy with my new system
I used to not be able to do anything else while rendering a video in SU. If i tried to browse the internet, it was sluggish and twitchy. I don't miss old my computer

PS I love knowing that if I were to go back and read this a few years, I'll be laughing at how outdated my quad core is compared to whatever will be available then. So future self, if you're reading this, please don't laugh too hard. Right now, I promise this really is a great computer
-
Chris, did you get your new computer from a website? If so, could you let me have the address of it please? Sounds like you've got yourself a good one there and is just the kind of thing I'm after.
(This is where Chris says he had to take out a second mortgage to buy it and I start to cry)

Has anyone come across the Alienware computers?
http://www.alienware.co.uk/product_pages/desktop_all_default.aspx
They are certainly.. distinctive to look at but appear to be made especially for the gaming and graphics market.
As I don't really know what makes a good computer I can't tell if these are any good or not
I ought to buy "PC's for Dummies"
-
Hey, I bought mine as parts and built it to try to save some money. Though from what I understand Dell sells a very similar machine for a little less. I'll look into later today and see if I can find the price. I think it is in the US$1,000 price range.
And yes Alienware does make great machines. They are a little more pricey than necessary because you are paying for the cool brand, computer box design, and bragging rights. Lots of people buy them for games for sure. But they have great hardware. They are definitely legitimate.

I'm guessing that if a computer is specifically designed for gamers then it will be more than capable of dealing with 3D modelling and rendering. Or are they handled in different ways?
-
They mostly have the same requirements. The biggest difference is that some of the upper end game ones have 2 video cards in them that sync together to give you twice the video processing speed. This is handy for games that are super high end grapghics. I am not sure if this is helpful in 3d modelling. It is expensive.
I like that Alienware page. Those are some great computers. I think for me I'd go for the green one (Area-51). Maybe someoneelse has some more thoughts on this though. Don't just go off my opinion alone, I don't keep up with computer specs like I used to
You might be able to find a better price somewhere else though

IIRC Alienware have some other tweaks they make to the system (the BIOS methinks) you wouldn't normally find on the exact same hardware.
-
Hmm.. I've just read some very negative reviews online about Alienware computers. I guess though that every company out there will have its share of negative reviews to some extent.
Whats the most reliable computer company? Dell? HP? Mesh?
