I've just come into some money (not a huge amount) and I was wondering if I would notice any difference from upgrading from a Q9650 to one of the newer Core i7.

I don't think any of the AMD chips can compete at that level, and I know that I would have to replace my motherboard and memory at the same time - which is quite a big step.

So my question is, would I see a huge performance difference? Or just a little one? Because if it's just a little one then it's probably better for me to wait - perhaps after the next Core i7 refresh which I think is just introducing mainstream parts.

I mainly game (using Vista 64) and program (Using Linux), and also some occasional video encoding (once or twice a month I convert 2hr MPEG2 into H264). Any thoughts?
