Whether or not you should go for the new one depends on your finances.
If you can pay for it in full, not put it on plastic, then go for it !
BTW, You do know Dell bought Alienware ?
If you are more interested in buying performance instead of a name, & can live with a normal case, you might want to look at the Dell XPS since they are pretty much the same thing.
On the unit you have,
I suggest you start by downloading Memtest86 & making a CD,http://www.memtest86.com/memtest86-3.5.iso.zip
Download & extract the iso image .
Burn the iso image to a disk using a program like Nero that has the "Burn image to disk" feature.
You can not burn the iso image to a disk as a Data file.
If you don't have a burning program that will do Burn image to disk downloaf ISORecorder ,http://isorecorder.alexfeinman.com/downloa...corderV2RC1.msi
Right click on the iso file & on the menu click Make Disk [or words to that affect]
Once you have the disk made leave it in the drive & boot the unit off of it
Let it run at least 1 full set of tests [I think there are 8]
If any errors are found, even 1
, the memory stick is bad & should be replaced.
If you have more then 1 stick & get an error try them 1 at a time to find the bad.
Memtest will keep running as long as you let it. It must be manually stopped.
Once you get the memory so you know it's good start the computer
Go to the Device Manager & uninstall the video card
Turn the unit off & unplug it
Remove the video card
Scrounge up one you are reasonably sure works right & try it.
