I would* get a h77 for that cpu, no point in getting a z77 board, this one is rich in features : http://www.amazon.co.uk/dp/B007RQ0MDA/
I'd get the i5-3470 which is less and spend in the 650 ti or 7850 for a card.
Apologies. The card I'm buying is the - EVGA GTX 650 Ti SuperSuperClocked 2GB GDDR5 Dual DVI Mini HDMI PCI-E Graphics Card.
Would the Asus be no good? That card you linked me to, does it support all of the other components I've listed above? Don't want to end up at stage one again. Does it support HD gaming too? Can't see any mention of HD 1080p.
(Please excuse me I'm a noob with things like this).
No, the asus board is decent and it's compatible, but the asrock board has more features for the money, and you mean board, the asrock motherboard has a hdmi port with support for that resolution, but since you have a card obviously you'll connect it to the gfx card, which supports also that resolution.
Any motherboard with the b75, h77, z77 supports that cpu out of the box, the same for the ram, i still recommend going with the asrock h77 pro4-m, it's almost at the same price as the asus, it's a better board, you don't need the gigabyte z77 for the cpu, unless you can get that board cheap, otherwise, get the h77.
