Kind of changed my setup alittle

but atm I'm using the HX620 with the following

i7 965 stnd. voltage @3.85Ghz //max so far at 4.2
6gb ram
DFI jr.
a 320gb samsung
and two 7200.12 500Gb
2x4830

about 4 fans, and a aquastream xt usb, (heatkiller 3.0 is nice!!)

now as far as i notice this setup runs fine.. i might try to use 2x4870 in the enar future
