Hurrah! I'm back at 200 in the world with a personal high a real possibility for the spring/early summer. I must replace the PSU in my dual 260 GTX i7 which stops & restarts every 15 min, no blue screen or anything just stop and start again, so something fundamental seems likely. It's not overheating either as leaving the basement door open & thereby dropping the ambient temp by 15 Celsius doesn't improve things at all.
TSBT aren't doing too badly either. Our graceful retreat from our high of 15th back down to 25th seems to have bottomed out and we are heading back up a few places, all being well.
