I mean it really depends on what type of games you'll be playing with the 8600GT. It'll run most games fine, it'll just start to struggle with really intense newer games like Crysis.
thx man on the comps
yeah I will be looking to change the video card first out of the system, but are there 8800Gt cards that don't take up two slots reason I'm asking is because this machine is a FFC and it does get a little tight.
Also the comp has only a 500w PSU will this be sufficient to run a power hungry 8800GT (the power supply does have the extra 6 prong power cable for the GPU)?
