i definitely wouldn't go any higher then a the 5770 a 1.8 ghz dual core is really going to bottleneck even the 5770. if your mobo supports overclocking you should definitely look into it. if you can't overclock, you may not want to go to a 5770 possibly a 5750 or lower
Yeah, after buying the parts for my rig, i looked into what OC'ing can do...and ended up on many forums saying i can take the E4300 up-to 3.2GHz...felt like bashing my head on the wall!
i havent tweaked with its features...only cos the board doesnt support OC'ing and thus thought it didnt have a BIOS reset switch...i'm digging up its info right now and from the link (thanx - jonnyboyC )
one option can be to invest in an Asus Maximus II Gene/Formula mobo and get past this issue - but what do i do with the existing board? ( lol - i can do that six months from now)
@ wa1 - yeah only setFSB was used by ppl but i'm open to suggestions
