bit-tech published a review of Inno3D's GeForce 8600 GTS iChiLL Xstriker3
At the higher price, you only have to look at the GeForce 8800 GTS 320MB's performance and measure that against its £165 asking price to realise that you'd be a mug to spend £140 on a GeForce 8600 GTS. Thankfully though, Inno3D's card isn't as expensive as other pre-overclocked 8600 GTSes and it actually comes in at a tempting price point if you're looking for an all-rounder.Inno3D GeForce 8600 GTS iChiLL Xstriker3 Review
Where gaming is concerned, the Radeon X1950 Pro will perform as well as Inno3D's iChiLL Xstriker3 and in some cases better than it too -- you can pick one of ATI's previous generation mid-range cards for around £85 (inc. VAT). Of course, it's worth remembering that the X1950 Pro doesn't have DirectX 10 support, but we think that's a bit of a moot point and more of a checkbox feature given the performance penalty for running current games in DX10 mode.
However, if you are looking at something that has all of the HD video acceleration features that are available in the current generation's mid-range hardware, you'll probably take the small performance penalty in games to compensate for the massively improved performance in HD video playback. Therefore we're not going to make an outright recommendation to buy this particular graphics card, but it's one to consider if the usage model outlined above fits you.
