I have an old computer I am messing around with. My question is will an 4x/8x agp card work in an agp slot that is for 2x/4x agp cards? Thanks
Yes it should, the same question was asked here, http://forums.filefront.com/tech-discussion/326866-agp-4x-84-4x-slot-question.html
Yes, it should work. The cards that are physically/electrically incompatible wouldn't fit in the slot anyways. I forgot to mention that in the other thread linked above.
