I have looked at pc pricing and can't see where i can get a i7 quad WITH 2 video cards under $1K
You don't need the latest and greatest PC to run your trading platform. Trading software don't take that much CPU power, mostly they are pulling data from the internet. But 6GB of RAM or more is advisable.
If you don't want to build your own PC, there are plenty of Dell Precision quad core workstations for under $900. Then you can add one or two extra basic graphics cards, for under $100 each.
I built the following trading PC three years ago, and it cost me $1,098 with 3 video cards. It's still way more powerful than I need, and I run TradeStation with 5 monitors and have at least a couple of hundred charts loaded at any time. I expect to use it for many more years to come.
