Since upgrading to a 6990 is out of my budget I've been considering crossfiring my current 6950 with a new 6950 but I have no idea whether this is truly worth it and if my PSU can actually take it.
Specs: Motherboard - ASRock 890GX-Extreme 3 890G Processor - AMD AM3 x6 1100T 3.30 ghz Phenom II GFX - AMD Powercolour 2 gb 6950 Ram - G.Skill-NT 8GB (4gx2) DDR3 1333 ram (intel 1155,1156,AM3) HDD - Hitachi Deskstar 3tb Sata HDD 7200 RPM Disk Drive - LG Blu-Ray SATA Writer PSU - Antec EarthWatts EA 650 Watt PSU Cooling - A-Power 120mm 2x Ball Bearing Case Fan
I did a rough check and found that the processor and the two 6950's would hit 540 watts (probably more) which i don't think gives me much breathing room. If i need to i can upgrade the power supply but i'd be hitting close to 450 AUD for an 850 Watt if i did and well a 6990 is only 300 or so more than that. So is it worth it and can my system take it? Also, should i get a better cooling system(if i need one, may aswell get a 6990)?

Antec is a good brand, they can handle more than 650W, all good brands can.
With the corssfiring, i crossfired my 6970 recently, was ive started to have issues with microstutting. Although when it wokred, it scaled good and gave very good results
I wouldn't run it on less than a 750 for long, but my system ran on a 650 Corsair for a bit until I got the upgrade.
