Hello, with BF4 coming out this fall I am thinking of adding a second 7790 so can still play with Ultra settings. My only concern now is will my old Core 2 Quad bottleneck a second 7790 and make running a second 7790 useless? My CPU is not currently mazing out when I play BF3 on Ultra but, I've heard some say that it may bottle neck with 2 cards though. What do you guys think? Will it bottle neck or should I just skip a second card? Also I'll take any suggestion for an inexpensive PSU that won't burn my house down.
GPU1: MSI Radeon 7790 1 GB OC Edition (love it, great preformance for the price I paid)
GPU2: If I do run with crossfire I will get a second MSI 7790 that's the same model as my current to reduce the risk of complications.
CPU: Intel Core 2 Quad Q8400 @ 2.66Ghz (LGA 775 socket)
Ram: 4 x2Gb sticks at 1333Mhz
OS: Windows 7 Professional
HDD: 1 Tb Western Digital Caviar Black
SSD: Corsair F120 120Gb
PSU: Antec Earthwatts 500w (I wil upgrade this to a 700w+ PSU if I do crossfire) Any recomendations on a good inexpensive PSU?
Mother Board: Intel Extreme DX48BT2 with the x48 Chipset (This motherboard is on AMDs crossfire approved motherboard list)
Thanks in advance guys!
