Evga have been around for a long time now, at least in sweden. My friend is a evga freak he buys everything with them. Evga claims to help with overclocking 24/7( at least did).
When I am going to buy graphic card I first check what gpu chipset that score the best for my budget. And when it comes to brand, I really don't think it matters. Yeah I know evga is usually great for overclocking, but if you are going to be overclocking you should buy new fans anyway.
But my tip is to don't buy a grafic card with less than 2gb of memory.
Here is a good test to see what chipset that preforms bests: http://www.overclock3d.net/reviews/g...tx670_review/7
nivida 670 seems to preform really great.
nvidia 670 vs amd 7770 http://www.hwcompare.com/12504/gefor...adeon-hd-7770/
I ony have 1b of grafic mem, I don't get bf3 to run great on high settings. Even if I would run cf I still would have problem in bf3.
