best miner for AMD GPU

[zvs]

ASUS R9-290XOCII 4GB is averaging 3250c/m using clpts in Windows.  Reports are that it's pushing 4500c/m in Linux

what about with the new windows drivers?

my 3gb 7970 can get up to 3700c/m in windows, though i usually run it at more sane settings and get 3500'ish.  290x should be a step above that and 280x similar

AMD HD 6670 1GB, test using AMD Catalyst 13.12, Windows 8 x64, G1610 CPU:
1. ominer 0.8, 425 cpm, fixed to upcpu, pool fee 2%, net performance user gets: 417 cpm;
2. PtsGPUz 0.4c, 380 cpm, pool fee 3% at ptspool.com, net performance user gets: 368 cpm;
3. ominer 0.9 preview 2, 336 cpm, fixed to upcpu, pool fee 2%, net performance user gets: 329 cpm;
4. clpts 0.2.2, 218 cpm, fixed to ypool.net, miner fee 5%, pool fee 5%, net performance user gets: 197 cpm.
Note: clpts 0.2.2 seem to be the fastest on AMD cards with 2GB or more video memory, but slowest on cards with 1GB memory.

It's hard to say, because the luck of pool may vary, so the blocks they find is not constant. After comparison, I am in ypool and 1gh pool, but that's for my case, you'd better try yourself.

sorry for newb question but which miner client and pool is best combo for ROI atm? thanks
