Suggestion for budget DOS based laptop for sound editing

I need a budget laptop for sound editing. I do not need a very high end hardware. I need a decent one that can play all my software. I am using three tools for audio editing. One is for the recording purpose. Second one is will analyze the video and remove all extra noise from it and the last one for making a final high quality output. I am right now using a Core 2 Duo pc where it takes long time to export the video. That is because of limited hardware. I want a budget system that must have a latest processor and it can provide me faster editing.

There are few model in the market but I found HP 15 r007tx as the best one. This one comes for Rs.36000 approx. It can be cheaper also. This laptop offer you a 1.7 GHz Intel Core i5-4210U Processor. This is a 4th generation Intel Processor. It has 4 GB 1600 MHz DDR3L SDRAM. I think that is quiet enough for running all type of software. For storage it offer you 1 TB 5400 rpm hard drive. The screen size is around 15.6 inch Screen and you will also get a NVIDIA GeForce 820M gpu on the same. Which is a 2 GB DDR3 graphic card.

The above one is best configuration according to me. But if you want a more cheaper then there is one model I had seen recently. Dell 3542. This one comes under Rs.29000. It is not a high end but I think it is capable fo giving you a high end output. It offer you a Intel Core i3-4005U processor with 4GB RAM DDR3 and the storage is 500GB. It has a Intel HD Graphics 4400 graphic support. This type of system are portable and cheap. I think this is the best choice for you if you are not planning to use a big size monitor on the same.
