Tom Burnqest :
I would safely bet you have never owned an AMD card. I would also safely bet you are bleeding green.
you would be losing on both bets.
however, that has nothing to do with the complete FUD and misinformation you posted.
firstly, the
560SE is not a rebadge of the the
460SE. they have difference gpus; the GF104 in the 460 SE has 228 cuda cores, 56 texture, 32 raster units and a 256 mem bus, whereas the GF114 in the 560 SE has 288 cuda cores which also has 48 texture, 24 rater units and 192 mem bus. the 560 SE being the last 500 series that nvidia would not be a rebadge since rebadges are the first cards released. the 560 SE is simply the left over, failed Q&A 114 gpus for the 560 to clear out inventory and were priced to compete with the 7770/7850 market since the 650ti had yet to be released.
also if you did own any previous nvidia cards there would be not a lack IQ on gaming due to AA which would be from having a more limited bus bandwidth since the 2xx, 4xx and 5xx series of nvidia cards have just as wide, if not wider in the higher end cards, as ATI/AMD at the time and also presently. i sit here with a GTX 570 @ 885/2000 that competes close to the performance of a 7870 @ stock speeds in many games with the same settings. along with not being able to increase the clock speed, because fermi is big, power hungry and hot, is the same problem the OP has with having under 2Gb of Vram.
FC3 with even lowered settings will use over 1Gb of Vram. i don't have much of a problem with 1.2Gbs and knowing how to tweak settings in nvidia inspector and not the CP, but the OP having just 1Gb is the difference. since you have all those nvidia cards; 275, 460SE, 560SE and the 570 maybe you can try learning how to tweak those drivers, eh? because if you're having problems running anything with a 670; its not the cards fault.
so any 650ti/7850 2Gb card or higher would have helped the OP. to state that their is a difference in AA quality between two different cards, since AA is AA no matter what card you have, is wrong and definitely smells of FUD. what is really laughable is AMD was shown earlier last year when the 7xxx series card were release to have worse IQ than nvidia because the drivers hadn't matured. but didn't have a damn thing to do with hardware . .
