I know all that.
But even tho the difference is very small, it is a difference. And its not going to get worse. Its free performance, even tho it may just be 1%.
And it so happens that i DO play with IGP just now.

Ive also had this ram a couple of years. When i bought them BFR was very common on this and other ram and it was actually a good price on them. More value at that time would have ment generic 1333 ram, so why wouldnt i buy this ram instead?

Anyways, this is off topic. The topic here is Vengeance 1866 and what they can do.
