Question  Compatibility and performance by Carlover1998

Hi Aria,

Just wanted to check if a Sapphire Radeon HD 4850 (which I currently own)would work in crossfire with a HD 6850, as i'm not entirely sure! Also, would you get a noticable performance increase in intense games? (As one PCI-E slot is 16x and the other is 4x)

I've also got a 650w psu (A CiT model with dual 12v rails at 20A each), will this be enough?

So would this all work?...

650w psu (CiT)
this mobo
HD 4850 and HD 6850 in crossfire
4gb ddr3 crucial ballistix ram (2x2gb)
phenom II x4 955 black edition
c-media pci audio card

Thanks alot, you're expert adice is greatly appreciated!

Answer by gavin on Friday, October 29, 2010
You can't crossfire a 48xx card with a 68xx card. That PSU won't be enough for 2 cards either.

Question  Question by Nik

Hi, I'm looking to put together a PC and just wanted to double check that this motherboard is compatible with these components:

*Seagate Barracuda ST3500418AS 500GB 3.5" SATA II Hard Drive
*Coolermaster Elite 370 Mid Tower Black (No PSU)
*Asus GeForce GF210 512MB DDR2 PCI-Express
*AMD Athlon II X2 Dual Core 260 3.2GHz (Socket AM3) Processor
*Arianet Stealth 750W "Silent" ATX Power Supply for AMD and Intel Motherboards 20Pin + 4Pin

I've read through all the specs and think everything is compatible, but just wanted some reassurance before i go to the checkout.
