Hi. I'm looking at buying a new Nvidia 8800 GTX graphics card but I'm a bit confused. When I look online for it, I'm given loads of results which all seem to be from different brands and yet all Nvidia:
ASUS NVIDIA GeForce 8800GTX (£250)
Nvidia 8800GTX (£230)
Point Of View 8800GTX (£250)
EVGA 8800GTX (£290)
XFX 8800 GTX (£380)

What's the difference between them? Are they all the same essentially but just tweaked by different companies?

Any particular one to recommend? I'm tempted to just get the standard Nvidia one (2).

I remember having this confusion last time I bought a graphics card a few years ago!
