CPU Bottleneck with 8800GTX?

Well for a GTX yes it would be bottlenecked. A GTS would probably fit nicer in you system. Firingsquad has a good review on how a GTX can get bottlenecked on different processors.

All this being said I think you've hit your last leg with a single core processor. All big games that are being released this year are going to be multithreaded. Valve, ID, Crysis, Microsoft are all going to take advantage of 2 or more cores. You might want to find some sort of upgrade path too a multicore \ DX10 system and what I would suggest is start with your processor. Move your way up with that and let more DX10 cards come out.

I agree with Prozac.

Hey Proz, check out the new sig. Just built her about a week ago and man I am lovin how responsive this baby is. lol just had to say that for some reason. Definite increase over my 3800+ X2 @ 2.40ghz w/ 2gb of DDR400 @ 400mhz and 2-3-2-5 timings! woot, lol

Best,

Hi...

This should help answer your question:

Well after much thought I finally decided to upgrade to the 8800GTS. However, I did also get an FX60 to max out my socket 939 as a final upgrade on this comp. Although this may not be quite the same as going with a C2D I think it should hold me off well enough into Vista, while still having DX10 and multi-core capability. Thanks for all of the constructive advice guys!

HAHA

Upgrading to a 8800GTS should give you a huge/significant boost. Upgrading to a 8800GTX may help you even more.

Once you have upgraded to these fast cards, upgrading your CPU will also help you quite a lot. You will be CPU limited for sure, but upgrading the card while retaining the same CPU will still help you a lot. Later you can go for a C2D.

I would advise getting E4300/6400/6300 over FX 60 and then ocing it past 2.4GHz.
