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. 


System Stats:

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!

Battlefield 3 scales very well and I would expect 4 to as well, so I would be looking into upgrading. While you are at it I would go ahead and get a 650-750w 80 Plus Gold (or platinum) PSU from Corsair, Enermax, or SeaSonic so you will not have to worry about having to change it in the next decade.

ASUS Sabertooth 990FX/Gen3 R2, FX-8350 w/ Corsair H60, 8 GiB G.SKILL RipjawsX DDR3-2133, XFX HD 7970 Ghz, 512GB Vertex 4, 256GB Vector, 240GB Agility 3, Creative X-Fi Titanium w/ Creative Gigaworks S750, SeaSonic X750, HP ZR2440w, Win 7 Ultimate x64
