Ok well I got a new computer about 6 months ago, so I can play some video games more smoother, however its still not as great as I’d like it to be, Im thinking its my video card because i have 5gb of ram, and not sure what else could slow it down. I have a link to my computer’s specifications page Product Specifications
The Geforce 8500 is not really suitable for games. It’s just a card to give you an image on the screen. I would say, get an 8800GT, GTS, GTX or an 9800.
New graphics you listed would give you better graphics quality than your current, integrated, card. The card you wanna buy tho is minimum for most of the new games, so you won’t get high frame rates.
Also in your computer you have 250W power supply while PNY (producent of the card you are going to buy) says on their website that the card needs 350W minimum… that will be the problem.
I have the 8600GT in my PC (well 2, but it makes no difference whether I have 1 or 2 for some reason :S). It plays Burnout Paradise on full, Crysis on medium, NFS Undercover on almost full, and various other games reasonably well.
