Minimum System Requirement for Algo Trading

I am planning to build an algo strategy which will ingest tick data for around 200 instruments, build realtime candle ohlc for different timeframes and has a backtrader engine to execute buy/sell signals in real-time.

I tried to simply ingest tick data for nifty and banknifty and my 3rd Gen core i7 laptop already started to sweat.So, those guys who have full fledged algo running with real time tick subscription on multiple instruments, what do you have or suggest to be a good specification for desktop for running such an algo?
