are You ready? Ready for what?
To be overrun by TeamChina!
They have taken off like a rocket

[chris]

I'AM ready, throw 2 GPU's in the race.... 3 units per hour someone with me ?

[Dirk Broer]

Already busy using a GT 9500, a GTX 260 and my HD 4770. GT 430 is chewing Seti WUs!

[chris]

Hmmm, units become a little bit bigger. 6970 now need ca. 45 min a unit ( earlier 30 min. ) 5770 need 110 min ( 60 min. earlier )

[Dirk Broer]

At least they bring up the old amount of credit again, 3,371.00 It had sunk with the old-length WUs to as low as 2,225.0
For benchmarking purposes: 4770 125 min. (was 110); GTX 260 84 min. (was 55 min)

[chris]

Grrr... have trouble with GPU driver 1.4.1523 ... the HD 6970 takes up to 85% of a CPU core with PG
HD 5770 have driver 1.4.1417 and takes max. 9% of a CPU.
Thats bad for WGC during the PG challenge mmmnnhhh.
But i will not downgrade the driver (gamehead also) ... after the challenge i will upgrade to the newest... maybe than its better.

[Dirk Broer]

nVidia GTX 260 uses 17% of the CPU, using driver 28.562 under Win7 Ultimate 64-bit with 4 Gb of DDR2-800 RAM
Asus HD 4770 uses 61% of the CPU, using driver 1.4.1646 under Win8 Dev 64-bit with 8 Gb of DDR3-1600 RAM

[chris]

HD 4770 uses 61% of the CPU, using driver 1.4.1646

So i see the problem isn't fixed with the newest driver
