I found one to buy at my location, but it costs around US$ 435
Should I get a second Radeon HD5870 for a CF?
My actual rig:
ASUS P6T | CPU i7 920 | CM Hyper 212+ | HD 5870 | 12GB 1600MHz @ 1333MHz | HD WD 1TB Sata II | DVD Pionner Dual Layer | Corsair 850W | Aerocool BX500 | AOC H428Pw 42" + LG W2353V 23" | W7 64 Bits | HT-C350 Sangung
The answer is no. Only if you can get one for around $150-200 would it be worth doing. You should wait for the 7000 series due in 1-3 months.
