Hi,

I am planning to buy the following gaming build (prices by alphacity.co.nz), in New Zealand $:

Thermaltake Litepower 700W Retail $89.95
G.SKILL Ripjaws X 8GB (2x4GB) DDR3 1600 (PC3 12800) F3-12800CL9D-8GBXL $79.94
Gigabyte GA-H77M-D3H LGA1155 $118.60
Intel Core i5 3570 Ivy Bridge 3.4GHz 6M L3 Cache LGA1155 $265.98
Samsung SH-222BB/BEBS 22x SATA DVD-Writer B $27.30
Seagate 2TB Barracuda SATA3 7200RPM 6Gb/s $134.80
Samsung 24" LS24B350H Gaming LED Monitor - 1920x1080, 2ms Response time $230.56
SilverStone RL01B ATX Mid Tower Case Black $50.08

until now I was fairly set on getting a factory OCed ati 7970, but the recent developments with the 670 and the new GHZ version made me unsure. I am planning to mainly game with the machine, ultra details on 1080p. The games vary, rpgs like skyrim, shooters like crysis or rts like starcraft 2 are included.

The question is, which gpu should I get? Options are:

MSI R7970 Lightning 5.6Ghz3GB GDDR5 PCIe Card, 697$
Sapphire HD7970 3G OC Version, 1000MHz / 1450MHz , 384bit 683$
Sapphire HD7970 3G PCI-E 3.0 925MHz / 1375MHz , 384bit 659$
Sapphire Radeon HD7970 3GB reference board 611$

Gigabyte GV-N670OC-2GD GTX670 2GB PCIE, 559$ (standing out for being a really cheap OCed version of the 670)

I am reluctend on spending 140$ more if I it would only make a difference of 60 or 65 frames for example. On the other hand I am worried that the 670 will not could it for every type of game, since I read that the ATI cards are way stronger in computing power but that most games dont utilize that power at the moment.

I know this is a hard question to ask, thanks for any help!
