I thought the Zoostorm would be better, since its got the new 2010 technology "Intel® Core™ i3 processor" its got 2.93GHz whilst the acer has 2.50ghz.
I found the same make http://www.ebuyer.com/product/176496 but the gaming version, its got a graphics card of
Graphics nVIDIA® GeForce GTS250 512MB DDR3 Graphics Card what do u think?
The Core i3 is Intel's current low end part, where as the Core 2 Quad is it's last gen high end part. The Core i3 is a cut down dual core made with lower power usage and cost cutting in mind. It's also over-priced for what you get because you're having to pay for the internal graphics processor that you won't be using. Also, MHz doesn't mean everything. If you're really concerned about it, it looks like it comes with a Foxconn motherboard, so you could easily do a bit of light overclocking.
The GTS250 is an OK card. It's not great, but it's OK. The GTS250 is actually part of a long line of renaming that Nvidia has done, and is actually a bit of a joke for people who keep up with this kind of thing. The GTS250 is a renamed 9800GTX+, which is a slightly overclocked and renamed 8800GT. It'll be able to run modern games just fine at 1280x720 (same as X360 and PS3) with medium to high detail settings.
Ah, for some reason I thought I remembered seeing that i5's didn't need DDR3, only i7s...
You're thinking of 1366 socket (i7 only) using tripple channel DDR3 vs 1156 (i5s and i7s) using dual channel DDR3.
