That is a picture of my memphis s motherboard, which came pre built in my hp desktop (I know, I am a huge idiot for buying a pre-build) but my concern here is that my desktop came with a single width card, but I am going to upgrade to a dual width card, but, as you can see above the pci e x16 slot, there is a motherboard heat sink, will that get in the way of the EVGA ggtx 750 ti gpu when I install it, also, that card should work in a pci e x16 1,1 slot, instead of a 3.0 with a rough 5% performance decrease right? Thanks
