Yes and no. Some 2P decent setups can be had pretty inexpensively for what they are. However, it's a redux of the desktop situation- AMD offers the parts mere mortals can afford, while Intel isn't really competitive until the prices get toward the top end. Two 2.0 GHz, 8-core Opteron 6134s can be had for about $560 for both and a suitable 2P board is $400-450. A dual LGA1366 setup can be had for about the same amount, but for the price the two Opterons and their board run, you'd either be looking at two E5520s (2.27 GHz, 8M L3, HT, Turbo, $775 per pair) on a bottom-end dual LGA1366 board or two E5507s (2.27 GHz, 4M L3, no HT, no Turbo, $540 per pair) on a nice dual LGA1366 board.
4P is doable with Opteron 6100s as well as you can get four 6128s for a little over a grand. 4P G34 boards run from a little under $800 to a little over $900. The killer here is the minimum of 16 sticks of DDR3 RAM you will need to get full performance. Intel's cheapest 4P-capable Xeon 7500 CPU sells for about a thousand bucks and it's only a quad-core unit. A good Xeon 7500 series CPU like the 8-core X7560 is nearly $4000. That's for one, not for four of them. They also need a bunch of RAM for full performance. Also, don't forget that 4P motherboards are huge, generally measuring 16.something" by 13", which dwarfs typical 12"x13" EATX DP boards and even the unusually EVGA SR-2 dual 1366 unit. You need a very large and very special case to fit those beastly boards unless you're great with metal-working tools and are willing to slice and dice a full-tower EATX case.
You also hit the nail on the head as far as RAM prices go, they suck at the present.
