What resolution do you play at and what power supply do you have?

The 9800GTX is rather power hungry, a second card will generally provide better performance however it seems that you have a P45 board, which i believe does not support SLI which would restrict you to single nVidia cards.

2 PCI-E slots does not mean that your board has SLI capability. SLI must be licensed and up until the P55 and X58 chipsets only nVidia chipsets supported SLI. You can run 2 ATI cards in crossfire however you cannot run 2 nVidia cards on your chipset. Your graphics upgrade options are restricted to a single higher level nVidia or ATI card, or 2 mid level ATI cards, 2 4850 will cost the same as a 4890 but perform slightly better.

I wouldn't spend money on another one of those. The architecture with the "8800" series with that 256bit memory inter face isn't worth a hoot and gains in SLI wouldn't be as grand as you think. Get a GTX260 or something newer from either camp.... 260/275/4890, etc.

There's also not enough video memory on the card ( 512 ). Get something with 1gig, regardless of what resolution you play at.

I would advice getting a 5700's series that is coming out tommorow that will beat the performance and have D11 support for future games wich will price 5770 $150 and 5750 512mb and 1024mb $109/$129 respectivly
