with a bios update, AMD A10-7890K (FM2+, AD789KXDI44JC, rev.A1, 4.1GHz, L2:2M, 95W)
Any room for intel at all?
An Intel CPU would not fit in an AMD motherboard; you'd need a new board too.
AMD quad cores are arguably somewhat like Intel dual cores with hyperthreading, though it's a little different. I was surprised with Ian Cutress of Anandtech recently started referring to AMD "quads" as 2-core 4-thread CPUs. AMD CPUs have modules, which each have two "cores" in them, which share resources. When both cores are active, they compete for resources and thus are not as fast as two cores that don't have to share resources. Hyperthreading, by contrast, runs a second...
I would not get the 7890K if you're running with a discrete GPU. Better to get an Athlon x4 860K or 880K, it's the same CPU but much cheaper because the integrated GPU (which you won't use) is disabled.

Hyperthreading, by contrast, runs a second thread on the same core, utilizing unused parts to get some extra throughput from it.
