I pay $89.94 usd per month to blizzard. I bought a 1 year subscription to ISboxer. I upgraded my computer. It was all worth it to me, I've already had many hours of entertainment. Cost is relative, in some bars a nights drinking can be over $100.

i 5 box and if you upgrade your PC I have two pieces of advice. 1) dont SLI, it's better to performance to get a better card than 2 lesser cards. 2) WoW is CPU heavy, not so much ram heavy. I have 64gb of Ram and never use over 15% or so, but my CPU is a AMD FX-8350 and while in Stormwind it's jumping up to like 90% utilization. It is 8 core 4.2 ghz. It works fine but maybe I should have gone with intel. For cooling I use the Corsair H100 liquid cooler and it is excellent. I played 20 hours straight last weekend and my cpu ran 38-42c the whole time. Make sure your case can mount the radiator if you go with liquid cooling.
