I have enough for it, people at the ncixforums are telling me though that it wouldn't really work with my computer and that it would be a bottleneck,
my system is the following:
DFI lanparty ultra-d UT NF4
Athlon64 3700+ oc'ed to 2.5Ghz
4x512mb kingston value ddr400
Mushkin HP550 (brand new)
so would getting the 4850 still be worth it or would it be bottle necked to the same performance as the 3870?
EDIT: and it is 100 dollars more if you add in tax and shipping and probably boarder fees
if its from the states, but I can get it for 185 before shipping and tax with instant rebate at ncix, and I hate MIR so it really isn't 159...
