Do I need / can I power a PPU?

[todesng3l]

Hey All,

I just built up a new rig specs below:

i7-950 oc'd to 3.9Ghz
6 gigs ddr 3 1600
Asus Rampage III Gene
Nvidia GTX 580 (EVGA OC)
Corsair 120GB SSD
1 Bluray/DVD Drive
750W Corsair tx PSU

I was wondering if I should throw in a dedicated physx card. Was thinking something along the lines of a gts 450.

Also I wondering if this set-up can handle the additional draw of the gts 450 using my current corsair tx 750w PSU?

I appreciate your help!

gts 450 is overkill for physx only, a 512mb ddr5 gt240 will be more than enough, but you won't see much of an improvement unless the game uses a ridiculous amount of physx effects like mafia ii.

And yes your PSU can handle both cards.

I have tried this with a 5850 and a 8800gt. I could not tell a big difference is games that use physx. I could tell the extra heat in my case.

with the 5850 only you can't even use physx, what you're saying makes no sense.

Wow, a single GTX580 is more than enough to run most of games with decent setting (maxed out) even without PhysX card.
Just try do some gaming first, see whether you're satisfied or not.

I caved and got an EVGA gts 450 FPB:

http://www.amazon.com/EVGA-GeForce-PCI-Express-Graphics-01G-P3-1450-TR/dp/B0041RRNBM/ref=sr_1_fkmr0_1?ie=UTF8&qid=1292561717&sr=8-1-fkmr0

only $114 and EVGA has a $30 mail in rebate brining the cost lower then the gt 240.

Although this may be slight overkill at least I will have a decent back up GPU should anything happen to my GTX 580.

I appreciate your input!
