What components should I get?

[zMartin]

Should I get the 4670k + Z87 G45 + GTX 660/7850
or 4670k + Z87 G43 + 7870
I'm going to get the 212 EVO and overclock the 4670k to about 4.2/4.3

Also I'll buy a 7970 later so is 600w enough for a 7970 and the 4670k or do I need a 750w?

Get the G65. That will be a dream board imo. It's only a bit more than the g45 too. Get the 7850 and save a ton of money, then wait until October when AMD launches their 9000 series gpus, then buy something from that line.

Get the GD65 , it has more power phases for more stability under stress and overclocking.

Get 650w:

The Z87-GD65 is £154, the Z87 G45 is £120. For £10 less than the XFX psu I could get a 600w psu, and for an extra £10 I could get a 750w psu, is the XFX really better? Also I could get a used 7850 for £135 or a new 7870 for £163, which one?

 

[Jackrzu]

Get the G65, the 7850, and a 650 watt 80 plus bronze at least psu from xfx, seasonic, pc power and cooling, corsiar, rosewill, nzxt, ocz, or evga

Then upgrade to a 9000 series gpu later on
