HD6850 crossfire

[brianthesnail]

Hi guys
well since my main rig is ok ive been considering adding a second HD6850 to my spare rig which specs are
core i3 3220
8gb ddr3
MSI Z77A-G41
HD6850(1gb)
64gb corsair boot drive and 500gb sata data drive
500w ocz stelthXstream psu
coolermaster CM690 chassis
obviously adding a second HD6850 will require a better psu ... i was looking at the VPF650 650W '80 Plus Bronze' Power Supply ( https://www.overclockers.co.uk/antec-vpf650-650w-80-plus-bronze-power-supply-ca-237-an.html ) however what are the aerocool psu,s like ( i have a aerocool case for my main rig and its impressive ) .. i was looking at the "Aerocool X-Predator 650W 80 Plus Bronze Modular Power Supply"( https://www.overclockers.co.uk/aero...us-bronze-modular-power-supply-ca-197-ae.html ) .. ive not seen many reviews on them so any advice
as a second pc would 2 x HD6850,s still produce the goods .. i play the majority of my games on the main rig but would run some older games on the spare rig .. any good
any advice would be appreicated
cheers guys

You would be better off selling the 6850 and getting something like a second hand 7970 / 280x for around £90

1 fast single card is always better than 2 cards as crossfire does not always work.

Also 1gb will be a big bottleneck compared to the 3gb of the above cards.
