if you can, definitely the first one, and get the triple copper cooler if you can also afford it..
The only problem i have with the graphics card is that i dont think it has VGA output.. So my current monitor which is kinda old wont work with the graphics card will it?
all you will need is a VGA to DVI adapter and a DVI cable, both of which can be picked up relatively cheap these days

1 x 2 METRE DVI-D CABLE (£5)
The adaptor I last used actually plugged into the graphics card and then you plugged the VGA cable into that, that's how the one PCS sent me worked anyways, so I'd check what adaptor you are getting first before ordering those cables rosgar.
Also how old is the monitor, can it accept a digital signal or will it require analogue, if it requires analogue you will need to check that the graphics card will output analogue - I only say this cos someone had that exact issue sometime last month I think - though that monitor was pretty old I believe.

looks good, would upgrade to the 1080p monitor for £20, definitely worth the difference
