GeForce 9900 GTX & GTS Slated For July Launch

[RPGWiZaRD]

You forget that GTX 260 will a lot more memory and games like STALKER and Age of Conan can easily eat up over 700MB with more to come. By the fall 512mb won't cut it for highest texture quality.

That depends what res and AA+AF settings. I'm on a 19" CRT and using 1280x960. For higher res 1680x1080 and above in most demanding titles 512MB might not cut it though yea.
