[SOLVED] PC is a lot slower after installing new graphics card.

[vodliedood]

Alright so I was using the integrated graphics on my i5 2400. It was all running smoothly, except for games of course. So I got an r7 360 and installed it. I had a HUGE boost in fps while gaming but my windows 7 ran like absolute garbage. My motherboard model is P8B75-M and I've got 8 gigs of ddr3 ram.

look like you switch motherboard, did you reinstall windows?
