"Despite the lack of HDCP support in the current version, XFX’s GeForce 8600 GT XXX Edition is probably one of the best bang for buck mid-range DirectX 10 graphics cards out there. From as little as £90 including VAT, the card delivers performance that is not too far off Nvidia’s GeForce 8600 GTS and, with a bit of overclocking, you can achieve practically the same performance as the 8600 GTS.
The cheapest GeForce 8600 GTS out there today will cost you around £110 (inc. VAT), which is another £20 more than the XFX GeForce 8600 GT 620M XXX Edition. First, you have to first ask yourself whether the extra £20 that XFX’s card costs over a standard clocked 8600 GT is worth spending, and then you have to ask yourself if it’s worth spending another £20 to get an 8600 GTS. Stretching to £90 would be worthwhile, in my opinion, but stretching to £110 will not make as much of a difference."
