If you don't play games, why bother? A V3 is more than enough. I had a V3 up until this month and it was great! Now I have a G2 GTS. I noticed that i can go at those super high resoutions, but that about it. The 32 bit color doesn't help too much. 2D quality is the same (I have a Sony G200, i kow when it's different).
Man you guys are demented for not using your Geforces. I at least download all the demos and watched the splender. I don't play too much games, but now I have an excuse to bust out my UT, Q3, and Cataclysm.
BTW, try use the S3TC Texture compression hacks for your games, WOW things are so much more details! AND you get more framerates! Man has there ever been such a win-win situation?
