Upgrading PC, need advice on what will fit

[Prestonian]

Hello, I'm upgrading my son's PC with a new video card, but with it being several years old I don't suspect up to date cards will actually fit the motherboard. So if I put up the PC's spec, would you be kind enough to recommend a card that will...A. fit the motherboard, and B...play Dark Souls2?

Many thanks.

Processor Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz 2.67 GHz

RAM 8.00GB

Motherboard ASUS P5QL PRO

The video card is a big ASUS one but I can't see any model numbers written on it. We're changing it anyway.

I'd recommend one of these:

YOUR BASKET
1 x Sapphire Radeon R7 260X OC 2048MB GDDR5 PCI-Express Graphics Card (11222-06-20G) £99.95
Total : £109.55 (includes shipping : £8.00).

The PSU is only a 550w one, is that enough for that card?

Also, is the processor good enough for the Dark Souls 2 game?

It is enough, i would recommend a gold label tho... more efficient.

What is gold label?

While I'm here, does anyone here know if that processor will run Arma3?
