As sightline stated above, for anything dealing with any kind of design work, I would go ONLY with the Dell Precision line on their business side. Higher quality for the same price plus better support hands down.
Again, I would HIGHLY recommend keeping away from any additional upgrade options on their site wherever possible. This means try to keep away from their ungodly high memory upgrade price by sticking with 6 GB or 12 GB (the lowest amount) and order the ram separately from Newegg.com you will save a ton. If you want to go with a full 24 GB of RAM I'd highly recommend the following from Corsair, it's some of the best RAM I have ever seen or tested, and just get two sets. It's probably still cheaper than the upgrade options available through Dell directly for that much RAM.
Corsair Vengeance 12 GB (3 X 4 GB) DDR3 1600
The same can be said about any video card upgrade, as usually they will charge you twice what the card actually costs to upgrade it from the base configuration.
Now this is just my opinion, but if I were selecting a Dell system for any kind of design work, this is what I would do:
Dell Precision T1500
Core i7-860 2.6Ghz 8MB Cache Socket 1156
Windows 7 Professional 64-bit
(2 GB DDR3 1333 non-ECC memory)
3 Year Next Business Day Warranty
nVidia Quadro FX 580 PCI-e graphics card
Firewire card
500 GB SATA 7,200rpm with 16MB Cache hard drive
16X DVD-Burner
TOTAL: $1,140
Add to that 16 GB of DDR3 Corsair Vengeance RAM with 4 sticks at $60 each and a second 320GB SATA 7,200rpm hard drive at $45 to create your RAID 0 array if needed.
GRAND TOTAL: $1,425
That's a a lot of savings compared to the cost of what your previous configuration was with very near similar performance. As an example, if you tried to configure the same options directly through Dell's site (with the full 16 GB of RAM and two 500GB hard drives in RAID 0) you're looking at a total of nearly $3,200!!!! That's HUGE savings by getting those parts yourself.
In fact, with the savings you could purchase two SSD drives in RAID 0 and have close to triple the hard drive performance as the original configuration of two 500GB SATA hard drives in RAID 0. Then use the standard 500GB hard drive as extra storage for data files if needed.
2 X Vertex 2 120GB SATAII SSD drives in RAID 0 at $230 each
GRAND TOTAL: $1,840
Benefits of the above configuration over the previous configuration:
- nVidia Quadro graphics card specifically manufactured for high performance design and content creation tasks.
- 2 SSD drives in RAID 0 offers up to three times the performance of 2 standard speed SATA platter hard drives
- 3 year next business day warranty
- About $800 savings and very similar performance.
