Finally, after months of waiting, we can now squeeze in a 128-bit, 128MB vanilla GeForce 6600 into our system. We chose Asus because of their reputation and because it was one of the cheapest 128-bit 6600s we could find. This is quite a boost and should future-proof our system against upcoming software and game demands for some time. We can now begin focusing more on storage, processor, memory, and motherboard upgrades. Then again, that all depends on how the market plays out.
