Difference between Swiftech blocks.
I've been after this block for a while as i know it's a favourite with a few people around here. And it's a great price.
But i've just noticed this Swiftech block that available to me for about £10-£15.
Would the drop in performance be that noticable that it would be worth paying the extra for the more expensive? Or would they both be the similar performance-wise?
