I plan to upgrade my video card that is the bottleneck now.

My current PC configuration is:

Videocard: Sapphire Radeon HD 5850 1 GB 256-bit DDR5
http://www.newegg.com/Product/Prod [...] 6814102884

Power supply: CORSAIR Enthusiast Series CMPSU-650TX 650W
http://www.newegg.com/Product/Prod [...] 6817139005

RAM: G.SKILL Ripjaws Series 8GB (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333
http://www.newegg.com/Product/Prod [...] 6820231275

CPU: AMD Phenom(tm) II X4 965 Processor BE
http://www.newegg.com/Product/Prod [...] 6819103727

Motherboard: Gigabyte GA-790FXTA-UD5
http://www.newegg.com/Product/Prod [...] 6813128415

Cooler/heatsink: XIGMATEK LOKI SD963
http://www.newegg.com/Product/Prod [...] 6835233081

Windows: Microsoft Windows 7 (6.1) Home Premium Edition Service Pack 1

My plan is to put 7870 CF, so I can hook up 3d Display like Samsung 750/700

Is the rest of my hardware good enough to to do, so? Especially my concern with MB because it is PCIe 2.0 only.

Thank you for the answers.

Crossfired would be a no. PCIe 2.0 will suffice without any noticable performance hit (even with 3x gtx 680s) but your cpu is going to bottleneck anything above that 7870.

Hi Mishania

I have just got a 7870 and am currently running eyefinity (3x 1080) and the card runs ME3 in 5760x1080 very nicely so you might not need to CF right away. (i have the sapphire stock clock ed)

as for the PCIe interface, my mobo is rated for 3.0 but the drivers are not utilizing the technology/bandwidth yet. I just looked at GPUz and the mobo runs at powersaver 1.1 speeds and then bumps up to 2.0 when I am running a game or a graphically intensive application so you should be fine with your current set up.

7870 Crossfire will be overkill and bottlenecked by the CPU. As for single, there is a good chance that the CPU will not bottleneck at stock. But if you do though, overclock the CPU, you can't go wrong.

PCI-E 3.0 cards shows very small difference when used on a proper 3.0 slot compared to the 2.0, so you shouldn't worry much.

^ your mobo will not support pcie 3.0 unless you upgrade to the newest intel cpus (3770 for example)

I have already overclocked CPU - it is running at 3.95 now. So, if CF is overkill should I go with 7950 or 7870 is still ok?
