Mig, check out motherboards using AMD's 780G chipset. This chipset comes with the ATI Radeon HD3200 gpu with an additional 64MB of sideport memory with DX10 support. Isa ka advantage when choosing 780G chipset is it is compatible with AMD's newer CPU's... so indi maayo kagasto when you feel there's a need to upgrade. Another feature is Hybrid crossfire, meaning using your onboard graphics + pcie graphics as one for added boost on gaming performance.
I recommend 2 boards nga imo mapilian....namely..
