Which video card for this Hewlett Packard?

[Syle]

My cousin is trying to upgrade his computer to be able to play Diablo 3. Here is the model:

http://h18000.www1.hp.com/products/quickspecs/12921_div/12921_div.html

The processor is the Intel Pentium Dual Core E2180 Processor (2.0-GHz, 1-MB L2 cache, 800-MHz FSB). He also upgraded it to 4gb of RAM.

The only problem is that the on board video card can't run it, so I am trying to find a replacement for him. These are optional cards that are listed as possible choices from the link above:


NVIDIA GeForce 8400 GS 256MB SH PCIe x16 Graphics Card
NVIDIA GeForce GT130 768MB PCIe x16
ATI Radeon HD 2400 XT 256MB DH PCIe x16 Graphics Card
ATI Radeon 3470 256MB SH PCIe x16
ATI Radeon HD 3650 (512MB DH) PCIe x16
ATI Radeon HD 4550 Dual Head PCIe x16 Graphics Card
ATI Radeon HD 4650 PCIe x16 Graphics Card
HP DisplayPort To DVI-D Adapter
HP ADD2 SDVO DVI-D Adapter

A) Which card is the best?
and
B) None of the cards above are listed as "PCIe 2.0" cards, and most of these come up on Newegg as PCIe 2.0 cards; will a PCIe 2.0 card work just the same?

Thanks!

Just did some research, and I guess 2.0 is backwards compatible, so I've got that problem solved. I'm just not sure which of these cards listed are the best.

Maybe there are some cards not listed that would be good options as well?
