You are good there then although solo mining BTC is pretty much an iffy proposition with the diff being so high, you may want to give LTC or PPC a try those are lower rate chains where you have good chance to get a block within reasonable amount of time then you could trade them for BTC.
I actually have my two least capable miners pointed at solo mining. One is solo mining LTC and the other is solo mining BTC. I figure since it's pretty much a long shot for me anyway until my first 5870 arrives either Monday or Tuesday I might as well put my two most useless miners (my cell phone is doing solo LTC at about 8 hashes per second (LOL) and I have the cpu on one of my computers soloing BTC at about 50 KH/s (again, LOL)).
Maybe not today, maybe not tomorrow, BUT some day at least one of those two miners will get lucky...
Then I have the rest of my miners pointed at OzCoin with liecoinpool.org as my failover...
Heh, good luck with that.
I tried solomining with CPU (3MH/s) for a week, no luck at all.
