if his dad will allows him to upgrade his graphics card seperate, he can stick in a junk graphics card stock, and upgrade a dell. were talking like over 250 dollar knockoff on computers, and it's instant. i saw that as the latest deal yet. although, sometimes it gets better, you have to watch the online coupons yourself. i remember getting this dell dual xeon computer with a 1,000 dollar knock off. only problem is you have to find a good deal and go looking for a coupon to enter in at dell. that's what my friend did too. and he upgraded his graphics card after. not sure if they have those good deals anymore, but i know they use to.
it's hands down the cheapest and best solution for his requirements.
and i can see where your dad is coming from, it's just cheaper, safer, and it's better to get a pre built. i have both and prefer prebuilts anyday. also, i fried so many parts it's ridiculous. just a headache to put one together too, not exactly fun.
oh also, my dell xeon has troubleshooting schemes with light colors, so you know exactly what's wrong with it. and dell support is far superior to custom parts and other companies. i've had flawless warranty phone calls that went well. but with other custom and companies, it's just a headache.
also, the coupon code is at 25 percent. so if you buy a 800 dollar computer, it's 600, and you have 200 for spending on a graphics card, but that's the worse case scenario i suppose.
again, games are graphics bound.
