Upgrade HP DC5750

[pbassett]

Since my 0A64h motherboard only supports a low-profile video card on x16, I need another motherboard for my new GTX 950.
How can I find the list of compatible motherboards? I would prefer to keep the CPU (AMD Athlon 64 X2 3800+ Windsor, Socket AM2 (940)).

The x2 3800 would severely bottleneck the gtx950. You are in need of a system upgrade should you wish to keep the 950.

Also, its your case that is imposing the low profile GPU restriction.

HP Compaq dc5750 comes in either a microtower configuration or the the desktop orientation that is called a "small form factor" system. HP 0A64H (Small Form Factor) Motherboard Specifications

You need a different case for the GTX950, i.e. larger case.
I think the thing that will cost the most is a new Microsoft OS.
You can get an AM3+ motherboard in Micro-ATX or ATX size. Also a bare mid-tower or micro-tower case.
You can get an AM3 Phenom II CPU cheap on eBay that work in AM3+ motherboard.
