How to figure out if my video card is compatible

[Thormx55]

Hello,
My computer is an hp pavilion media center m8120n TV PC that I've had for god knows how long (http://h10010.www1.hp.com/wwpc/ca/en/ho/WF06b/12132708-12133156-12133158-12133158-12133158-80230858-80450713.html?dnr=1) I want to upgrade the graphics card in hope that I can play some more modern games my current upgraded video card is a GeForce 8400 GS, I'm looking to upgrade to a GeForce 9800 GT but I don't know if they're compatible

Yes 9800gt will work. Can you tell your budget for gpu as we can reccommend some other.

Since your motherboard has a PCIE slot then yes, you could run a 9800 GT, you could even run a GTX 690 (space & PSU permitting). PCIE is backwards compatible.

Edit: A Radeon 7750 would be a better option as it's slightly faster than a 9800 GT but I don't think it warrants the extra $30. As ASHISH65 already implied, a lot is determined by your budget.

GeForce 9800 GT $57
Radeon 7750 $87
Radeon 7770 and Antec 450W PSU $141
