decided to keep running my current system for a while longer, but have an easy chance to upgrade a bit as a friend wants to buy my HD 4870 1gb to crossfire with his HD 4850 512mb. the card is currently paired with my HD 4870 x2 in trifire for decent frames in BF3 with mixed settings, but for the difference of about $40 i could slap in another x2 for quadfire and maybe push another 5-10fps. i haven't, and won't bother OC'g the GPUs (which might save some volts).
my question/concern is if my PSU will buckle under another power hungry GPU... ???
