I found a BFG Geforce 6800 Ultra OC on craigslist for $50 (used). The card looks tempting but I was wondering can my pc handle it. I have a 430W PSU and in BFG website it says I need 450W PSU. In my computer, I have Core 2 Duo 4300, two 7200 rpm hard drive and two dvd-writer and 3 fans. I dont really need a graphics card like that because I only play flash games in internet browser and do some word processing in this computer.. But for the price it doesnt hurt.. My worry is that, if I buy the card and plug it in my computer, my psu is gonna blow up.. Anyone have experience with this card?..
