Kraeoss :
This is my current
board or should i just focus on getting a better cooler (i have a coolermaster hyper 212 cooler) and push up cpu OC. i have a XFX AMD 6870 card 1GB version.
i'd have liked to get more Slots for SATA devices though, but is it wise to invest in SATA expansion cards ?
As for PSU i have a Thermaltake 750w.
That mobo has 6 SATA ports: 2 SATA III and 4 SATA II, which should be adequate. A spinning HDD's
sustained transfer rate cannot saturate a SATA II connection, much less a SATA III. If you need more SATA ports, an expansion card is definitely an option, but isn't 6 ports enough for your current objectives?
Cooler Master makes several variants of the Hyper 212. If it is the EVO, it should be capable of cooling a 4.3 or 4.4 GHz OC, it may just need to have the dust blown out of the fins with a can of compressed air.

You may need to stretch your $150 budget to get a meaningful upgrade in GPU capability.
Your TT 750 W. PSU should be adequate, except for MAYBE Xfire. For that we would need the specific model #.
