ok first, im new to the forum but ive been using this page for a lot of time for my upgrade path =), hi everyone

the next thing is that im upgrading my video card (an 8800gt), and have this problem, i know the 4890 performonce better than the 5770 (as seen in this forum reviews and benchmarks), but the problem is that dx11 seems tempting and that i own a monitor that its highest resolution is 1280x720, my problem... is at that resolution you would see too much difference in performance between these 2 cards, and if dx11 is worth my sacrifice in performance

i dont plan on change the monitor for at least 2 years from now, and at that time i could go crossfire for any of those cards, or change them for that matter, thou unlikely to change monitor any time soon

i know that, for example, dx10 never "lift of" like it should be, and im a little "scared" that i go for the dx11, lose some performance, and never got what i really want (REALLY dx11, STALKER CoP screens barely make any difference, but that is a "launch" game for dx11, same as Dirt2...)

5870 or 5850, are out of price range imo, and for that resolution those card would OVERKILL my monitor

sooo should i go with the 4890 or 5770 ? too much diff in performance for that res. ?

thanks =)

my specs are

CPU: Phenom II 955BE @3.6Ghz (OC)
MoBo: A790GXM-AD3 (DDR3/SLI/Audio HD)
GPU: XFX 8800GT 512mb
RAM: 3gb DDR3 1333Mhz
PowerSupply: 650w Corsair

but how it will be the performance ? enough for new games ?, im expecting something like 45 fps, crysis enthusiat, with no AA... for example, or 60 fps on BFBC2, something like that

someone I saw sold their 1 week 4890 to buy a DX11 card for AvP because the difference is so big...

oh, and there is almost no performance hit to run DX11 in AvP (maybe 5% at most from what I could see)
