I found that sticker but it only says 240 V 12.0 A.

You don't have a big sticker like this one?

If you don't, I'm not sure how we can find out that information. How old do you think it is? You might be better off getting a new one all together.

[QUOTE="fireandcloud"]you had a pretty good card and then you replaced it with a card that performs about the same and now you're wondering why it's not running faster? O_ofireandcloud

I'm wondering why it runs slower. I replaced it because I wanted the ATI in another PC.

well, i'm sure the 8800gts will perform better on some games and the 2900xt will run better on other games. they're about the same in terms of overall performance, so you shouldn't expect better performance necessarily.

I defenitevely shouldn't expect worst performance on Crysis.

why not? they're almost equal to each other in overall performance. some games the 2900xt will do better on; some games the 8800gts will do better on. it just may be that the 2900xt does a better job with crysis than does the 8800gts. two examples of 2900xt outperforming the 8800gts (unfortunately, this chart doesn't have crysis performance comparison):

Those Comparissons are irrelevant. He has the XFX 8800GTS 512MB. It is the G92 model which is much faster than the 8800GTS 640MB which uses the G80.
8800GTS 512MB has 650Mhz Core clock and 1940Mhz Memory Clock while the 8800GTS 640MB has 500Mhz Core Clock and 1600Mhz Memory Clocks.

If the G92 GTS is doing worse than the 2900XT, then there's definately a problem.

You NEED to figure out how many Watts the PSU has. There should be a sticker on the side of it that lists all the information. Find out the watts, and how many amps it has on the 12v rail. There should be one or two ratings for the 12v.

It's very likely that your PSU can't handle the new card and it is being underpowered because it's not getting enough juice. You can't just assume everything's fine and that the PSU isn't the problem. This should have been one of the first things you considered when upgrading to a new card.

If thats all the PSU says, then its definately a junk PSU

Maybe you don't have a good enough PSU? What powersupply is it? How many Watts?

This is because the card auto decreases performance if it is not receiving enough power

I think the power suplly is 250 Watts 12A. I'm not exactly sure.

The point in installing older drivers is that the newest version doesnt always work properly with the rest of your configuration. So its always good to try multiple drivers when you are encountering problems.greatmax1

I might try that then.

The PSU is definately your problem. The minimum recommended PSU is of 400Watts. Read the manual lol. Also there is no use getting two video cards if you don't even have enough power to run one properly. Get a 500Watt PSU and you'll be running Crysis beautifully with your card.

About OEM, its totally irrelevant. The is no difference between OEM and the retail appart from the fact that retail comes with a fancy box and manuals. OEM is just the hardware therefore is cheaper than the retail version.

The PSU is crucial component which people often leave out. A bad PSU can even damage your hardware. Invest a little more on a decent PSU to ensure optimum performance
