cooling a gtx280

[slamz]

right, i need a bit of help.
i have a wc loop i'm in the process of building. its going to include a swiftech mcr220 rad, swiftech apogee gtz cpu block, laing DDC1 with xspc top pump, swiftech mcres micro res, 7/16 tubing, 1/2 barbs etc. so its going to be a cpu only loop.
i am planning on buying a gtx280 in the very near future, and was wondering what would be needed to cool it, and whether one more 220 rad would be suficient? (as this is all i think i can fit in my case)

thanks.

What's the rest of you system look like? Generally, two of those rads should do the job quite nicely.

got an antec 900 case, one rad is going in the front, then, if i get another, i'm going to mod the top, and put it there.
also got a gigabyte p35 mobo(want a evga 780i but they seem to be dissapearing off the shelves), q6600 (stock settings), ocz 600w psu.
