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

[dcdave78]

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

Will the 2900XT run at full potential? Probably not.

But upgrading the CPU won't really be worth doing for the small performance gain, in games.

 

[dcdave78]

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...

Bottleneck? Yeah, I would say so.. But I would still go for it... some would argue that the 8800 would be a better buy, but thats not what this thread is about, is it? So yeah, you will bottleneck.. but you will still see a gain.. Looking forward to DX10, but IMO.. why upgrade from the beast that can play just about anything on MAX/HIGH, when there are no DX10 games... I mean, why not just wait and get it for cheaper or get something better for the same $$, I see no downside to waiting with that x1900XT 512.. W/e that just my opinion. Whatever floats your boat man.. Good luck!

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

You don't understand how a CPU bottleneck works, do you? Even if the HD 2900XT is being bottlenecked, it'll still outperform the X1900XT by a fair margin.

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

Go ahead and wait several months until M$ releases DX10 for XP after slow sales of DX10 games due to Vista being a crappy game platform force them to do this action(I had to reinstall battlefield 2 under XP, cause it ran like crap in vista, i have 2G of ram mind you). Or wait for the 65nm shrink. I personally have decided to just buy the mainstream card of each generation when it comes out, though i think this time around im just gonna go ahead and buy top of the line of previous gen. But im just a highschool student with no capital income.

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

you know, I wonder ifthese people need to update their reviews, and test if theres bottleneck problem lik ein the 8800GTX with the 2900XT

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.
