Upgrade CPU / MB or add another 6950?

[Predator]

Hi

I currently run an AMD Phenom II 955 Black Edition 3.2Ghz clocked to 3.6Ghz on an MSI 790FX-GD70 with 4 x 2GB OCZ PC3-12800 1600Mhz RAM and a Saphire 6950 flashed to 6970.

So... I'd like some opinions as to whether its best to upgrade to an i5 2500k or add another 6950?? As I have my eye on this;

I have an 850w PSU. Only game at 1920 res, but finding games like Metro 2033 really do hammer the PC.

Imo I think you should get an aftermarket cooler, overclock the 955 to 4.0Ghz+ and get another 6970, save you a little.

what brand psu have you got?

Its an Antec Quattro 850 that I bought Oct'07. Lasting really well!!!
