Yeah, are you cool with building it? Just say yes and I'll configure one that will destroy the one you are planning on.
yea lol any of us would be happy to... only problem is that 17" LCD's cost probably $150 for a decent one....
so then the budget is probably actually around $200-260 after monitor keyboard and mouse and speakers and w/e else u get with it...
but yea, for a budget gaming pc you'll probably just want an athlon 64... w/ cheap mobo... 1gb memory... cheap case, cheap dvd burner, cheap w/e else lol...
and then a decent video card, for rct3 you shouldn't need much, but i wouldnt go with an x200 haha... id go with an x1300 over that... and thats not even a good gaming card.
give us $550 before the monitor + peripherals (essentially $350 for the box) and you should be able to play rct3 just fine.
