Are there any problems with this memory spec wise? Also Is there any incompatibility issues between my planned build and the RAM? My biggest concern is the heatsink and possibly the GPU. Also since its a 10% off sale for RAM on Newegg is there any better RAM available for around the same price? Thanks for your time.
