Hi guys, i need help, i recently managed to buy a HP Workstation wx6400 with dual intel xeon 3.0GHz chips, 4 GB RAM 80GB hd.
i paid £200 for this and chose this over a new build with an AMD bulldozer 6x setup.

1.Was this my first mistake

i should probably say that im a student so will be using the typical student software, but also alot of AutoCAD and CAD based programs,
i picked up twin Dell 19inch monitors for £70 and chose them over 2x 20in samsung syncmaster for £110

2. Was this also a mistake?

then due to the tiny hdd and i tend to download quite a bit, i bought a samsung f3 1TB internal HD for £70

3. is this any good?

and now im contemplating RAM, the motherboard can take up to 16GB but i think 8GB would be enough, plus my budget is reaching the bottom of the pool and i have seen some RAM for £20 or so but im not sure if i should wait and buy a more high spec ram or would it even matter (by that i mean will i even notice) because ill have 8GB so it should handle most things i throw at it, shouldnt it?

sorry to write such a lengthy post but i really need the help

n.b i have had a little bit of a rush of blood to the head and bought all of this in a little bit of a frenzy alt=":hammer:" /> i know im dissapointed in myself but come on.... who hasnt

cheers guys

You need the RAM that goes with the motherboard you've got - some won't be supported. Have you had a look to see which graphics chip and processor will be best for AutoCAD? I can't recall it being that hungry but haven't used it for a long time.

In order (and I think you mean xw6400 rather than wx6400).

1) No it was not a mistake. The Bulldozer CPUs are heavily optimised for multi-threaded server workloads and have proved to be less suitable for lightly-threaded user tasks than more conventional CPU architectures. I doubt you'd have seen any advantage over your twin Xeons.

2) The HP workstations usually come with workstation GPUs (ATI/AMD FireGL I believe). You should find that your CAD software is rather happier with this than it would be with a consumer graphics adaptor. The usual rule for monitors for CAD work is "bigger is better" though....

3) Nothing wrong with Sammy disks. I use 'em.

4) 8Gb should be adequate. Looks like it takes DDR2 667 (PC5300) memory, buffered and registered.

This is all very 'high fallutin' stuff. I recognise most of the words but they make no sense to me. My hat is off to you 'techies' I really don't know how you figure all this stuff out. Deep respect. Concrete
