Given the performance and features that you are looking for, you're probably going to be a little over $1,000 for your final budget for a good performance desktop system if you go with Ivy Bridge and the latest chipset platform. Here's the system we recently did:
- Intel Core i5-3570k 3.4 Ghz Quad-Core LGA1155 processor
- ASUS P8Z77-M PRO LGA1155 mATX motherboard
- Corsair Vengeance 16 GB (2 X 8 GB) DDR3 1600 CAS 9 memory
- Intel 520 Series 120 GB SATAIII SSD
- Western Digital Caviar Black 1 TB 7,200 RPM SATAIII 64 MB Cache hard drive
- ASUS Radeon HD 6450 1 GB Silent LP PCI-Express 2.0 graphics card
- Corsair Enthusiast Series TX650 V2 power supply
- Lite-On DVD-Burner Black SATA
- Fractal Design Core 3000 ATX mid-tower chassis
- Cooler Master Hyper 212 Evo CPU cooler
- Arctic Silver 5 thermal compound
- Windows 7 Professional 64-bit OEM
Total Price: $1,175
I'd also recommend you taking a look at some possible upgrades including:
PNY Quadro 600 PCI-Express 2.0 Professional graphics card +$100
Corsair H80 Liquid CPU cooler +$60
If you're looking at a true workstation-grade system, including Xeon processors and workstation graphics while keeping the ability to run 32 GB to 64 GB of RAM, I'd suggest the HP Z210 or Z420 series of workstations for you. We don't normally do too much with pre-built systems, custom-built desktops are my specialty, but we recently worked with some of these computers and I am incredibly pleased with their quality, performance, and value. In fact, we will be using many more of these HP systems in the future I believe. You're looking at closer to $1,500 for a workstation-grade HP Z-series computer, but it really is quite a deal when you compare prices elsewhere stepping into the Xeon-based and Quadro-based workstation systems.
