Given that the motherboard has an appropriate expansion bus for the 
video card, you should be able to use it without problems.  (And, 
TTBOMK, if you do so and have your BIOS set to disable the internal 
graphics when a discrete card is in use, it will shut down the onboard 
graphics, gating power to it such that it takes basically no power at all.)

Now, whether "a year or so" is long enough to wait for "AMD 
compatibility" (read "someone to write drivers for the AMD graphics 
cards that are as good as nvidia's when used for video playback") is a 
whole other topic.  I've been waiting "a year or so" since around 
2002...  In the meantime, I use nvidia cards in my MythTV frontend 
systems and all my other systems--that don't do video playback--use AMD.
