Something outside of that.
First and foremost, I strongly suggest a trading computer is a dedicated machine. All it does is trade. It does not do the newswires, it does not do backtesting, it does not do gaming, etc.
But if you're insisting all of this happens on one machine, here's my take:
As much RAM as you can fit in the box. To do all of that with 16GB RAM is not smart in my opinion. Your programs run in the RAM and RAM is cheap. The more you have going on, the more clogged your RAM will be. To do everything you're saying, get 32 or 64GB of ram.
At least 4 cores at 3.0gHz or higher. Consider even more cores.
For the gaming you'll want a high priced graphics card. I don't do gaming so I'll stay out of that one. Go to a gaming forum and ask what they use. If you go light on the gaming card it's going to push over to your cpu and you don't want that.
Now let's talk brand. Dell is the only way to go in my opinion. Use Dell Small Business and you'll get great service from English speaking persons in the USA who do whatever it takes. Don't have a small business? Just use your name as company name - it works fine and they're fine with it too. There's a guy on here named Scat who is a pro in Dell resales (whatever they call that) and he'll find you a kick ass box on the cheap. You can always buy your RAM from Newegg after you get your box.
I have messed with computers since the 1970's. I own more than 30 computers today. I have bought them, built them, written code, I have robots that build robots and they all run on computers, etc. and I've used them for trading during the most volatile times in history, etc. and never missed a beat. If you biuld or buy what you proposed in your post, you're going to be stumbling. I would guess that on today's market you'll spend $1500-$3000 to have a good, reliable box to do what you want.
Another suggestion, use that laptop for a dedicated trading box and buy a new multi-task pc that's not critical and won't cost so much. That way the critical machine is the trading box; who cares if your gaming machine locks up.
Good luck!
thank you sir!
What exactly do you mean by a "dedicated trading box"?
Is it just to place orders on a brokerage website?
The need for me to upgrade my current laptop is because it can't handle 10+charts at once. So if by dedicated trading box consists of running multiple charts and placing orders...I don't know if that will be a go.
