1. Check ur motherboard compatibility.
2. u might have an AGP, PCI, or PCI-e express.
3. Check your power supply, u might wanna buy a new one.
4. Check you moniter's resolution. Know it since u will game on it.
5. Check your motherboard's specs, Nvidia (SLI), ATI (CROSSFIRE), or both (X58 chipsets).
6. If u have either i suggest u stick to it. Dont buy Nvidia cards on crossfire motherboard or viseversa.
7. Now this is the most important part PEOPLE CHECK YOUR WALLET.
Now after you have checked your wallet there is still 1 Tricky thing NEW GRAPHIC CARDS ON OLD CPU.
Having an old cpu with a high-end card can be really frustrating as the card will be much faster than ur cpu.
Either upgrade or ATLEAST overclock.
Before u buy ur card add RAM increase ur RAM atleast have 4 gigs.
Upgrade your OS to a 64-bit version. If u have 4 gigs of ram and u add the card u will lose RAM, as if u added nothing.
NOW, u should not judge a card on its performance if it fails with the NOTORIOUS games i.e. stalker clearsky crysis and crysis warhead.
