hello there. i'm about to start a gaming rig build. need help with something though. i was shopping around looking for budget pieces but good pieces. i live in cincinnati so i have a near by micro center. there i found the processor i was looking for athlon 2 x4 640 for only 95.99 10 cheaper than the egg. as i was reading there ad they had a mobo in there biostar A780L3G AM3 760G mATX Motherboard if pair with the athlon 2 x4 640 was free so i read some reviews and thought it'll work. the video card i have selected is also from microcenter evga gts 450 for 119.99 94.99 after rebate cant beat it. it is dx11 i'm getting windows 7 so thats all fine and dandy. as i was looking at the mobo pic thought next to the pci e slot where the video card goes it says dx10. does that mean that this particular mobo only supports dx10 video cards and lower? this has confused me and any help would be greatly appreciated. thank you for your time
