If I use a PCIe 2.0 x16 card in a PCIe x16 slot with DDR5 memory would I be creating a bottleneck? Im looking to upgrade a Radeon HD 2400 to something a little better, but don't want to waste money on a higher end card if my bus cant' take advantage of it. Also any suggests on GPU mfg? I've heard mixed reviews. Any opinion would be appreciated.
Also representation of the current card in place. I dont know just how much clearance I have in length because of that heatsink at the end of the card. http://img9.imageshack.us/i/1106090927.jpg/
I'll be a bit limited in lenghth as well as width (most likely only room for a single slot card.
