i'm getting a new gaming rig in about a week and i need to choose a GPU.
at first i almost got 2*6870 in CF but then i've started reading nasty things about crossfire, mainly microstuttering.
I have a very sensitive eye to this kind of things so i'm having doubts about buying 6870's.
for the same price as the 2*6870 i can get an oc'd gigabyte 570GTX (this version: http://www.gigabyte.com.pr/products/product-page.aspx?p...).
from what i understood it can be overclocked even further to reach nearly 580GTX levels.
I know that crossfired 6870's are still a lttle faster than the OC'd 570 but i'm afraid of the problems which are usually accompanied with crossfire systems.
i will be running the games at 1080p.
the system i'm getting is this:
I5 2500 @ 3.3GHZ
8GB of ram (4*2)
fractal design core 3000 case
620/750W seasonic PSU (if i'll go with CF than i'll get the 750W)
Scythe KATANA 3 cooling for the cpu
i still have to decide which MOBO to buy (depends on which GPU i'll decide getting)
2*500GB WD caviar black HDD's (already have them)
so i have a few questions:
1. how bad microstuttering really is with 2 6870's?
2.will i be able to max out all the new games at 1080p with the oc'd 570GTX?
3.do i need to buy a specific MOBO in order to have the ability to overclock the 570?
4.how difficult is overclocking the 570?
thanks in advance for answering!
p.s. sorry if my English isn't good, it's not my native language
How good do you need to be? A single GTX570 will run very well with a single 1080P monitor.
A GTX570 needs only a quality 550w with 38a on the 12v rails plus two 6-pin PCI-E power leads. Even a GTX580 needs only 600w.
Seasonic is one of the best brands, stick with them.
You do not need a special motherboard to overclock a GTX570.
I would not bother overclocking a graphics card. The chips have been binned already, and the best chips are used in factory overclocked cards so that they can be sold at a premium. The price premiun for a factory oc'd card is not that great, and you mostly get what you pay for.
But, you do need a P67 or Z68 based motherboard to be able to overclock a "K" sandy bridge cpu.
I suggest you get a 2500K instead of a 2500. The cost increase is minor, but you can then overclock the 2500K from it's default of 3.3 to 4.0-4.5.
If you do not plan on sli, you can buy a cheaper micro-atx sized motherboard that is cheaper. It will only hold one graphics card plus 3 extra expansion slots.
i guess i'll go with the I5 2500k ocerclocked to 4.3GHZ (the store where i'm buying does the OC)
and probably the 570GTX oc but i'm kinda worried about the 1.28GB of vram, is it enough for games like BF3 at 1080p and ultra settings?
