Hello
I'm lagging in every game I play, so I susspect that my motherboard or CPU is a bottleneck, so I'm thinking of buying a new one. I just do not know what, and why. So if you could help me and give some pointers I would greatly appreciate it!

I currently have:
Motherboard: Gigabyte GA-870A-UD3
CPU: AMD phenom(tm) ii x6 1090t processor 3.2ghz
Graphicscard: MSI N750Ti TF 2GD5/OC - Grafikkort - GF GTX 750 Ti - 2 GB GDDR5 - PCI Express 3.0 x16 - DVI, D-Sub, HDMI
SSD: Kingston SSDNow SV300S3B7A/120G
RAM: Kingston hyperx genesis ddr3 2x4gb khx1600c9d3x2k2/8gx

Best regards

CPU is good enough to run almost every application/games smoothly, so no problem from CPU, RAM is even not a problem. Motherboard cause bottleneck in case of GPU, if you install PCI-E x16 3.0 in 2.0 slot then it will cause but not so much. You can barely notice it. But for CPU, it will only bottleneck if motherboard is not powerful enough to reach processor to its true strength. But motherboard is not problem there may be because it is compatible with this processor. I think, its your GPUs causing bottleneck. Both GPU's are of different model(i.e. one is MSI and other one GF GTX 750 Ti). Make your drivers updated. Its better to use single powerful card than two. Try to maintain there temps also.

You cannot run SLI on your MB, NV cards need 8 lanes each to run SLI. Your MB has only a x16 and x4 slots at 2.0. You could run XFire if you had AMD cards, perhaps that is the problem. There is no performance difference between 3.0 and 2.0 with 16 lanes.
