Would a GTX 660 work in my system till I get a new MOBO/CPU?

Hello,

I have some money to spend on upgrading my PC.
I want to get a good GPU now and get a new motherboard and CPU later.
I can just get a GTX 660 now, I know it will be bottlenecked by my CPU but I'm getting a new CPU in a few months.

So my question is: Are there gonna be any more compatibility issues when I put the GTX 660 in my system?

System Specs:
CPU: Amd athlon II x3 450
GPU: GT 440 (Will be replaced by the GTX 660)
MOBO: Biostar n68s3b with PCI-e 1.0 slot for the GPU :( 
RAM: 4GB 1333mhz
STORAGE: 500GB HDD + 60GB SSD boot drive
PSU: 450w don't know the brand though.

The pcie 1.0 slot will hold back the gtx 660 a little and the athlon will also bottleneck it. Also could you tell me what is the brand of the 450w?

It will work fine providing the pSU can handle it.

Check on that "450W" PSU. If it's truly capable of 450W, and is "balanced" for a modern PC (e.g. 33A or more available on +12) it will be sufficient. If it's cheap junk however (Raidmax, Logisys, Apevia, Diablotek, Sunbeam) it will die violently, possibly taking other parts with it into the fiery abyss.

Are you sure it's a PCIe 1.0 slot? http://www.biostar.com.tw/app/en/mb/introduction.php?S_... <- if it's this mobo then I would be surprised that any AM3 / DDR3 mobo has PCIe 1. If I'm wrong, apologies :) 

EDIT - never mind, I see nVidia didn't use PCIe 2 until MCP72 and your mobo is MCP68, apologies (no post delete button?!)

Taken right from the motherboard manual

"PCI-Express 1.0a compliant"

I looked into the machine and I'm afraid I have a pretty shit PSU, It's an MS-TECH MS-N450-SYS

I wouldn't risk getting the gtx 660 and running it on it . Better save up some money and get a quality power supply like a cx 500 or an xfx 550w

I can get a OCZ CoreXStream 500W PSU with some money I wanted to get new headphones.
But then I have to know for sure that the card will work with the PCIe slot in the motherboard, Somebody said to me that I could run into some problems with the old slot, errors and such.

The GTX 660 needs a PSU with atleast 450W though

the corexteam 500w is good enough to run the gtx 660

The Antec VP-450 is the cheapest PSU I'd recommend. Although efficient enough for 80+, it is disqualified for not having active PFC (needs a little voltage switch). It will have no trouble with a GTX660.
Still, the original question also concerns the mobo slot, and about that I'm not sure.

Thanks, I'll get the Antec PSU. I looked on the site of my local pc store and I can test the GTX 660 and return it if I don't like it. So I will test how it works out with the motherboard.

You could run it on a 380 watt from a reputable psu manufacturer no problem, the rest of your system is very low power

Can't I use the current PSU that I have right now then? And do you know how much of a performance loss do I get from having a lower PCIe slot?

No, your current PSU is probably junk that is not actually capable of producing what is on its label, or doing it cleanly. Attempting to use it could damage attached parts if it either dies or the heavy load causes it to wander out of spec.

Ah, Okay. Then I'll just get a new PSU :)
