Some Graphic card held and advice needed

Hi folks.
Gotta say, this site has been quite informative so far, but one question remains.

I'm the owner of a motherboard which has the VIA K8M890 chipset. It has a PCIe x16 1.0a slot.
( details: http://www.foxconnchannel.com/prod [...] -us0000306 mot )

Now, my graphics cars burned out recently, and I decided to give the board some upgrades. I'm on a budget, so going for expensive things isn't an option, but while I'm putting in the new card, I'll throw in 2gb of extra ram (on top of my 1gb) and a better processor (Probably to this AMD AM2 Athlon 64 X2 4200+ "EE" 2x2,2Ghz).

So, the graphics card was the issue. I was thinking about getting a ATI HD4650 1024MB Gainward card, but that is a PCI-express 2.0 card, while my board has a 1.0a slot.

I did my research, but I can't get anywhere close to a definitive answer. "Yes", "No", "probably" and "probably not" were all answers I got.
Then I got "It'll work unless you have a VIA chipset" answer.

Now I'm confused and worried. Finding older graphics cards is kinda hard in the area where I live, and it seems that everything is made for 2.0 nowadays.

So will the card work? And if not, what card would you advice me to get?
(And will there be a bottleneck problem with that card/cpu combination?)

Are you sure about that?

Don't get me wrong, I appreciate the answer and effort you took to help me, but I'd hate to buy a card that I can't use. (Like I said, budget and all that.)
I read some posts about 2.0 cards and VIA chipsets, but I can't find anything definitive.

You have the very typical issue that almost all VIA chipsets have with PCI Express cause they didn't follow the specifications to the letter. That means that they have issues with backwards compatibility when a PCI Express 2.0 card is put on it. The fix is rather easy but you need a friend with a non VIA chipset mainboard to flash your graphics card.
