I have just got a offer for my 4200 x 2....must be the overclock, I got mine on special offer and got it really cheap (£150) about $270, well I have been offered £220 for it! so I may sell it and move onto another project, might try the San diego 4000 with the 1MB cache and try for 2.9 gig on air! and with the change I will perhaps get a gig of faster Ram for a nice overclock, I am pretty lucky, I always seem to be able to sell for more than I pay which funds this extravegant business! there is a special offer on in the UK at the moment on the 4000 for £88 which is about $145 I suppose. Never really use the dual core much, spend about 70% of my time gaming so little benefit (apart from really good 3D Mark 2006 scores if that counts) and I will probably go for a Conroe when the prices have come down a little at Christmas. This really means that I can keep myself interested until the mid to high end Conroe's come down in price a bit and I can treat myself at Christmas to a new CPU (again), Mobo and Ram. This bug is getting REALLY bad now and I need to keep away from these forums for a while! Anyways what I wanted to know is how do current owners of the 4000 find it and what kind of overclocks are they getting, I have good modded air cooling (see my specs for the 4200 x2) and was wondering what was a realistic target for the 4000, I am limited by 1.55V on my mobo and it's not worthwhile for me to change the mobo bearing in mind my Conroe pursuit at the end of the year. I have heard the Sandy even in 3700 guise is a good overclocker.
