Is this enough power for the graphics cards I want?

[bchill]

I'm planning on running two EVGA GeForce 9800 GTX+ Superclocked Edition graphics cards, found here:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130385

I think the PSU requirements for the card is 450 watts, but if I have 2 does that mean I need a PSU with at least 900 watts? I was planning on going with this one:

Thanks ahead of time, Bc.

Yeah that PSU should be good, but I would get a gtx 260 or 4870 1gb instead of two 9800gtx+

it should do ok

but i'd get a 4870 instead....

That PSU will be more than enough.

+1 for 1GB HD4870.

So one of these:

Will be much better than the two 9800's GTX+ SC Edition?

Even if it's not, I think I'm going to get it anyways and just get another one in a few months or so.

Also... how much better is the 4870 than the GTX 260 I just linked?

let it tell you


the 9800s might be faster than the 260, but dont get the 9800s, if ur planning on using CUDA or Physx get the 260 if not get the 4870

the 4870 is faster if ur not using physx or CUDA

Eh... sorry for asking what seem like such basic questions, but I'm really new when it comes to understanding the technology behind computer parts, etc. This is my first time really diving into the understanding of computers components. I'm not exactly sure what CUDA, and if I'm not mistaken, all I know about physx is that it's used when playing games. This will be a gaming-based machine if that helps you help me decide as to what graphics card(s) I should go with. I plan on using it for warhammer, crysis, valve products.. mainly games such as those. Sorry for my lack of knowledge on this subject, but thanks for providing me with some help with this. It's much appreciated.

i would grab the "old" gtx260 which can be found for 200$. the are very powerful.
as for ur psu a good 600w is enough.

That's just silly. For a lot less than getting those two 9800GTX+s you could get a single 9800GX2

You don't even need an SLi board for that one. If you already have an SLi board though you should consider getting one 260 now, and then picking up another one latter when more demanding games come out.

do u do a lot of video encoding or other cpu intensive tasks? if so that is wut CUDA is used for mainly, it uses the gpu to assist the cpu, if you want to know more about it : http://www.tomshardware.com/reviews/nvidia-cuda-gpu,1954.html
although it isnt very useful right now it hopefully will be in the future

yes, physx is used in games, it makes things react as if they were real (or at least tries to lol) ive never used it myself, if you google it u should find LOTS of reviews and comparison pictures/videos
http://en.wikipedia.org/wiki/PhysX
again physx isnt widely supported but will be on future games\

if u dont care for these features then go for the 4870 definitely

or even a 4870X2 which is currently the fastest card that u can get right now but it is way overkill
