Great, I can wait for the Vapor-X series, besides there's other work I need to do on the PC.
The 6850 will do well w/ my PC but I'm not so sure w/ a 28" or 30" monitor.
If you look at the link I provided there are game benchmarks all the way up to 2560 x 1600 resolution. If you are getting a 2560 x 1440 or 2560 x 1600 resolution monitor, then I highly recommend you wait for the Radeon HD 69xx series. They will be single GPU video cards and are expected to be faster than the HD 5870, but slower than the HD 5970 (a dual GPU video card).
