Yes but I would like to support a 24inch monitor; though your point is taken the 460 might be adequate. Then again between now and end of Dec the 6850/6870 might drop (esp if someone offers a nice sale during blackfriday/cyber monday period. Stil the overall point is taken that if the sale is for the GTX460 I should consider that route as it is still 1.5 to 2x faster than the 8800GTS (and supports dx11) assuming it can handle 24inch without an issue.
Monitor is 20inch 1680x1050 😀 At that resolution with 4AA, an HD6850 is only 2% faster than the GTX460 768mb that costs $130-140, and an HD6870 is only 9% faster than a GTX460. Doesn't seem like $360+ videocard setup is a good "bang for the buck" for 1680x1050.
