Expect to pay more than $100 for both a good video card and a decent power supply. You do want better than what the computer comes with.

"Great PC to build on!!!" Just purchased this PC. Out of the box, it runs very well, pretty much plug it in and away you go. My goal was to build an inexpensive gaming PC and this is the perfect one to build on. I purchased the unit, then the next day I bought an ATI HD Radeon 5750 video card and an Antec 650Watt Power supply. Took about 15 minutes to install. Now my wife can play sims 3 at full settings and I can play Starcraft 2 at Ultra settings. All together I spent uner $800.
So at least it doesn't have a proprietary power supply.

Everything so far about his computer has been great. I read the reviews and decided to go to Best Buy and pick one up. I'm planning on using this for gaming, the only problem is the power supply is only 300W (for anyone who was wanting to know). But you can pick a 450-500W power supply for $49.99 most places, which I'm going to do so I can put in a nice graphics card.
So we know the power supply it comes with is only 300 Watts, and will need to be replaced.
