Will a 4800 X2 @ 3GHZ bottleneck a ATI 2900XT 512 MB

I have a 4800 X2 939 socket proc running at 3 GHZ will it bottleneck a 2900XT I have been thinking of upgrading from my x1900XT 512.. I don't want to buy another proc until the AMD quad's arrive ... And anybody interested in buying my X1900XT 512 make me a offer at Dc_Dave78@Hotmail.com... any feedback on the matter is appreciated....

Regards

Dave

So is there any advantage to moving to the 2900XT at this point other than it will play DX10 games which are not available yet...

I'd wait for Crysis or any other decent D10 game. By that time the card will be cheaper, and your XT is fine for now

Idk if you were talking to me.. But I get it.. Its pretty straightforward.. 8)

Thats good stuff... DX10 + Xp = More money to spend on a vid card instead of vista.. or to save..

CPU bottleneck usually occurs at low resolutions where your frame rates are so high you can't even tell theres a bottleneck (unless you plot a graph).

Say you had a CPU that could only pump out 60 FPS, the performance would be no different at a low resolution than it would at a higher resolution with all settings maxed. You'd be getting 60FPS either way because that is the performance limit of the CPU. At extremely high graphic settings the Vid-Card would begin to struggle whereas the CPU is kicking back with its feet on the table.

For example, check out the following chart:





Here we can clearly see the mid-range system performs better at low resolutions, whereas the slow-CPU/fast-VidCard system performs better at high resolution with AA/AF.

The low end CPU can pump out 100FPS but when you crank up the resolution performance depends more on the Video Card. Seeing as the mid-range system has a slower video card, its performance is lower than the high end card when graphic details are high.
