1680 x 1050 > 580 or 570?

[Floriante]

I will buy a new card but cannot decide between these two cards.

My monitor's resolution is 1680 x 1050 and i want to be able the play all the games at highest settings without worrying.

So is 570 enough for this res and 580 is overkill? Or shall i go 580 to be able to play everything smoothly?

Both are overkill for 1680x1050.

Yeah, you don't need anything over a GTX560Ti. The 570 will provide plenty of power, even if you upgraded displays.

I'd avoid the 570 due to lack of VRM. The 580 has 6 phases, while the exploding 590's have 5 over the 4 of 570's (all the same type). 570's aren't as bad as the 590 in regulation reliablility since they make up for it from the lack of extra shaders/ROP's, an NF200 onboard etc. Though they still crap out on people. Enthuasiasts are still concerned about their VRM failures. So I'd stay away from reference designs with those. If 570, shoot for the 570 Classified which is built of a 580 PCB.

If not, then a reference/Twin-Frozr 6870 or 6970 (2 GB) would also be a great choice as long as you don't prefer nVidia drivers over AMD.

As for being overkill, depends on what your goal. I'd suggest anyone to do a FurMark bench at 1680x1050 then at 1920x1080 to see how much difference there is. A few FPS. The difference in pixels between the two is low, so it's not like running 1024x768. Also, it'd help a bit on "playing all games at highest settings without worrying".
