the bottem one but why dont you go for AMD instead of pentium m8 AMD is better for gaming then go for a 1g memory sice then add another 1g in it for better gaming, you need a good G'card aswell.
I agree, go with an AMD system. VAIO's are pricey, so Id say you have quite a budget, so go to www.cyberpowersystem.com or www.ibuypower.com and configure an AMD64 system with the same budget you are looking at with VAIO, and you will have a PC with a 3 year warranty, life time tech support, and it will beat ANY Vaio easily... If you want to MSN me, my MSN is darkmoon767@comcast.net if you want me to walk you through configuring a cyberpower or ibuypower system. PM if you would like my help with the above,
