Yoshi,
haha my sysmte is as follow:
Celeron 366@550
224ram PC100
Abit BE6 (not revision 2!!)
Quantum LM Plus 20G
SBlive!value
Rogers@Home Cable.
Sony 17" Multiscan 200ES
Like u said, no point to upgrade to a GTS with a celeron.

so this generate another question... What other things should i upgrade?
Anyone know how fast the CPU my motherboard can handle?(Abit BE6 not revision 2!!)
I want to buy something like a P3-700e and oc it to 800+, possible? need another upgrade?
I want to upgrade monitor, cpu, ram..... simply just want to buy a new computer for a low low low low price.
