Yeah, kind of confusing isn't it. I'm going to go out on a limb and say it doesn't really matter...they are different manufacturers but must adhere to specs to build the card.
Look for:
DDR5 Memory, 1G or 2 G
Cooling...lots of fans is better (but louder too)
Pick a brand you trust...I like Gigabyte and MSI but I am not sure they are not really any better than the others.
Yeah that's pretty much what I thought, but wasn't sure. I too prefer Gigabyte, but wasn't sure if there were better brands for the same price. It is interesting though that most of the cards only have 1 fan, while all the Gigabyte ones have 2-3 fans.
Right now I'm leaning towards the Gigabyte 560 Ti from Newegg
The card comparison site puts the 560 Ti above the 6870 in FPS, but below in regular specs, which I thought was interesting, and if the 560 Ti is better than the 6870 in FPS, and the 560 regular stats are just barely less than the 560 Ti, then I would assume that the 560 regular has better FPS than the 6870 as well.
From what I found price wise:
Statswise: (my current card) 5750 < (much) GTX 550 < GTX 560 < (barely) GTX 560 Ti < 6870
But if you take FPS into account, 5750 < (much) GTX550 < 6870 < (assumed) GTX 560 < GTX 560 Ti
All of the following are Gigabyte variants:
6870: newegg - $190, $160 with rebate (also has free shipping so there's another $8-9 off)
GTX 560 Ti: newegg - $235, $205 w/ rebate
GTX 560: newegg - $190, $165 w/ rebate
GTX 550 Ti: newegg - $130, $110 w/ rebate
Pretty much comes down to Brand preference.
ATi 6870 has the best stats and for a great price, while the nVidia GTX 560 Ti has the best FPS for a slightly higher price, with it's slightly lesser variant being only a few dollars more than the 6870.
Sorry for such a long post. Just thought that since InkSix and I share the same problem, this might help him as well.
