Will gtx 480 and 8800 gtx on 750W work?

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?

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.
