Okay so i was looking around on newegg today and found a 3870 for $99!, now here is where the dilemma is, i thought i already had my computer together.
e7200
evga 8800gs
gigabyte ga-g31m-s2l
2gb ocz ddr2 800

Should i downgrade the cpu to an e2180/2200 and buy the 3870? I just wanna use this comp for gaming and i never encode videos or anything like that. I want to oc either of them, the 7200 to about 3.8 and the e2180 to about 3.2, so would it be worth it to pull the trigger on the 3870?
