Im wondering if my PSU can support the things I want to install.

My Current Specs:

Mobo: Asus P5E3 Deluxe : http://www.asus.com/Motherboards/Intel_Socket_775/P5E3_...
Video Card: GTX 480
Ram: 2x 2gb 1600mhz : http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Cpu: Core 2 Duo E6850 @ 3.0ghz
PSU: 750W: http://thermaltakeusa.com/Product.aspx?C=1264&ID=1907#T... (this might be the letdown)
Hard Drives:250 7200 rpm and 300 gb 5000 rpm

I want to add...

1. another 4 gb of the same ram: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
2. put in my old 8800gtx 768 MB, 384 bit to use as a physX card
3a. add this or something like it : http://www.newegg.com/Product/Product.aspx?Item=N82E168...
3b. i would take suggestions though on what may be better than the delta case fan.

im not sure if hard drives use up any considerable wattage but i could easily remove one of them but im guessing they dont.
thank you for any help :)

you got a beast card but your cpu and ram sucks(sorry bro).i would suggest upgrading your cpu/motherboard/ram if possible.

i know my cpu sucks now (after almost 5 years) but its temp is fine n its working and the reason for that ram is because its the most my mobo supports. to buy a new mobo/cpu would cost more than i have right now. my budget atm is like around 100 dollars.

i figured id get the most out of spending around 100 dollars by spending...

$30 4 more gb of ram
$10 on artic silver 5 (to fix my old gtx 8800 cuz i sadly never replaced the thermal compound on it)
$30 - $50 on a fan or something to cool things to make up for putting in the 8800 gtx. ( i dont care how much noise is made)

since my cpu is behind, i thought using the 8800 gtx as a physX card will help lighten the load since then my cpu nor gfx card will be bothered with that.

save your 100 bucks for now,collect some and grab a i3 2100/h61 setup.

is that that marginal a difference between the i3 3.1ghz dual core and a core 2 duo 3.0 ghz?

also im not familiar with new boards so which board were you specifically referring to?

The GTX 480 will handle the load by itself just fine. The GTX 8800 requires a Minimum of a 450 Watt power supply, I am not sure if this is the case as a physX card but a good 750 watt power supply should be fine for what you are doing. You are just going to be bottlenecked by the rest of your components.

i thought putting in the 8800 gtx as a physX could help reduce the bottlenecking since physX usually uses a lot of CPU or gfx card? if you could correct me or whatnot on this, id appreciate it :)

Slow/low ram can be a bottleneck
Slow/Old CPU
Slow/Old GPU's
Dated Mobo's that only support pci express 1.0 or 1.1, etc...

Right now you'll never see the maximum potential of your 480GTX because your cpu is old and inefficient compared to SB-IB chips, even the i3 suggested beats Phenom II X4's and your chip is not even a Core 2 Quad chip. The 8800GTX is only going to handle PhysX computations, meaning only when PhysX is supported by a game and is happening on screen will this help in handling load while having all the bells and whistles.

Everything else looks/good and adequate but you shoul definetly save for a new mobo and CPU. If you really want to make it worth the save, opt for i5 over the i3.
