A lot. The 6600 XT is PCIe 4.0x8 (8 of the 16 pins aren't wired up). Even at PCIe 3.0x8, you only have access to half the bandwidth of the card. The full bandwidth may not be necessary in all cases, but there are times when that's definitely going to hurt performance. At PCIe 3.0x4, you're now talking 1/4 of the card's bandwidth, which is very much going to hamstring its performance.
