He might find himself wishing for more of a constant 60fps+ feeling, or he may want to give the next COD game a try. He might even decide to check out BF3 if it turns out to be as epic as it might be. Who knows, but much like my attitude on firearms, bigger is usually better
Prices as they stand, it makes no sense for a desktop buyer who wants to game to buy a Llano, unless they *have* to have an itx box with no discrete card at all. Which would end up pretty disappointing if you can only play older titles at low resolutions/etc. Same $$ can buy a much more powerful PhII rig with a better GPU, although you do miss out on USB3 with the affordable mobos afaik. That's a cheap remedy for those who care though, with $20ish PCIe cards for that purpose.
Now throw MC deals/stacking rebates/etc into the mix, and it starts looking more attractive, as in the scenario below where someone mentions being able to get by on it until they can afford a real GPU. I'm thinking around $120-$160 AR for a mobo/llano, and that's a pretty good entry point. At $220-$240, it's just too much when you consider the performance you give up compared to even a GPU from a couple gens back like a 4870. Hell people have been linking to GTX460s AR in the rough $100-$110 range, that's like a supercharged V8 compared to the LLano's 1.5L i4, or the Intel HD integrated's moped.
