Hi guys! im thinking on upgrading my rig overall when haswell comes out and have saved about 1.2k so far(im aiming for a $3k budget (Singapore $) by the time haswell comes out) but im not sure what to upgrade.
I have not overclocked my system or SLIed my GPU before so im not sure on how to go about it, but im tempted to try it once haswell comes out.
My current rig specs are
CM 690 2 Basic ( 2x 120mm casing fans and one 120mm side panel fan)
I7 870 + CM Hyper 212 Evo with a GT on the spare fan bracket
Nvidia GTX-670 Leadtek reference card
Seasonic 620w PSU modular
Crucial M4 SSD 128GB
WD 1TB Caviar Blue +500GB Caviar Blue HDD
Im not sure if i should downgrade to an i5 in haswell or stay with i7 as i play quite alot of demanding games and frequently my system does lag/stutter quite lot in game. not sure why is that happening..
