Hi all, need to know if it's worth upgrading my video card. I currently have a Dell demension 9200, running Vista 32bit, intel P965 chipset, 2.66 quad core(Q6700), 2gig ram, Nvidia 8600 GTS. Dell 3007WFP-HC 30-inch widescreen flat panel monitor. I was looking at the XFX GeForce GTX 260. I don't know how this card would perform with my system.
