Wassabe sauce forrumites, do you think given my current rig I will be able to run two 9800gtx+ in SLi?

Hello
from:
http://www.nvidia.com/object/product...x_plus_us.html

Thermal and Power Specs: (one (1) 9800gtx+)
Maximum GPU Temperature (in C) 105 C
Maximum Graphics Card Power (W) 141 W
Minimum System Power Requirement (W) 450 W
Supplementary Power Connectors 6-pin x2

Intel Core i7 920 takes 130W
plus power for hdd dvd drive and fans
let me check power requirements for drives and I'll post back

It should be enough. I would generally recommend 650w if you had a single card , so the extra 200watts should be enough for two. It's also a decent brand power supply with enough amps and good efficiency so you should be set.

Though I wouldn't bother with Sli as the price to performance ratio is awful. It roughly yields a 30 to 40% increase in speed and not the widely assumed 100% increase.

I would normally completely agree with you emosun but it seems my current 9800gtx+ must be bad since I upgraded the psu today and my system was still artifacting and restarting the machine( I posted yesterday asking if it was the card or insufficient power) Any ways Asus is going to RMA my card but being such an uber nerd I cant wait the 2 weeks to get that card back so I sprung for a new EVGA 9800GTX+ to get me by, figured worst case when the asus gets repaired I'll drop it in for SLi. Either way I cant be without a computer for that long or I'd go insane so another 9800gtx+ is cheaper than a 280 or 290 and this waty i wont have two different cards lying around.

Agreed with Emo. Unless you are playing at massive resolutions, or want Crysis at ultra, a complete and utter waste of money.
