Compaq, for the most part, uses nominal to substandard parts.. I wouldn't use a compaq again if they paid me.
Most of the hardware there looks pretty good, with the exception of the MB, and video card. The Motherboard is decent, but not tops and you're paying tops price on this.. Also, the Video card isn't an "Ultra" version and that makes a big difference in both resolution ability and FPS. For the price, you should be getting an Ultra...
I'd also want to know who made the Ram.. If it's made by crap.com or they won't tell you, don't bother... The optical drives look good, the HD is tops, but...... who the criz is Hugebee?? lol..
Um.. all in all, it's a descent system, but I think it's a bit over priced. Especially if the Ram is poor quality.
Check out this link.... It's a buildout list for an AMD system.. As you will see, even with a Gig of Corsair on twin sticks with heatsinks, and a 19" monitor, I'm coming in under the price you have there and all of the parts that I have on the list are high to superior quality.. (the CPU is a little slower too)
Don't skimp on the details when buying a PC.. It'll cost ya later..
