Acer Laptops :are they crap ?

Acer makes a cheap prodcut period. They user lower end plastics, as well as assembly. (I hate working on Acer laptops)

If budget is an issue then get an acer... though for $50 more you could get a gateway that will smoke the acer in terms of quality.

For a laptop though i would suggest one of the DV7T's from HP or a Business class Toshiba/HP/IBM (not the lenovo branded, the Thinkpads)

If you prefer, you still can revert it back using the factory restore procedure, there's a hotkey on every new acer laptop/PC. just my two cents

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
