Looks like the classic case of someone being short on budget for a comp and buying all worthless crap and then buying an uber graphics card thinking it would make the whole thing awesome. You shoulda just bought like a 4800 or 9800, or even an 8800, and then getting a dual core with decent clock speed and nice ram and an 80 dollar mobo with at least one pci x16 slot. Also what is your PSU, I wouldn't go under 600 watts if you are going to have a card that power hungry, 800 would be a safer bet.
