I just ordered a PowerColor AX6670 1GBK3-H Radeon HD 6670 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card and it doesnt have enough space to fit on my motherboard which is the M2N68-LA. Someone please inform me if they know a solution. The video card is a pci express 2.1 x 16 and the motherboard slot is pci express x16
