I have an Intel D915GAG motherboard from Intel (technical specifications). I installed Windows 7 on in before I realized that Intel does not support running Windows 7 on this motherboard. In fact, according to Intel the motherboard only supports Windows XP. But Windows 7 seems to run just fine. A quick check of the Windows 7 system requirements appears to confirm that the motherboard with operate with Windows 7.
What am I in for in the way of performance? Are there special drivers (unavailable from Intel) that provide enhanced performance, without which the motherboard will perform less than optimally?
