Hm, gaming builds are a little difficult with that budget but I'll see what I can do; do you need an OS, monitor, keyboard+mouse? And are there any parts you can re-use from an older computer, like hard drive, optical drive or case?
just the base unit actually ill just re-use my monitor prolly just windows vista or 7 if i can get one from my mates or a linux, but yeah just motherboard and such...well can you help me to find a budget spec.
do you think i can get a hybrid SLI or with 3-way motherboard that is compatible with AMD Processor? also what is the best cooling for the cpu that will maintain a normal temp instead of getting overheat or something.
Possibly. There aren't any as far as I know, but if you go with the HD4870 then the motherboard I picked out has Crossfire (ATi's version of SLI). There's also CrossfireX (three-way Crossfire), however I haven't seen any motherboards with it.
also what is the best cooling for the cpu that will maintain a normal temp instead of getting overheat or something.
prolly i need one a new PSU as well, ermm could you re-qoute it though with a xfire compatibility :-s, i just need a decent gaming system..not too extreme.
