Hi All,

I would like to upgrade my XPS 8900 so I can play GTA 5 without lag/shutter while driving fast. In addition, my current wireless (802.11bgn + Bluetooth 4.0, 2.4GHz, 1x1) does not support 5g network. Can I also upgrade my wireless card?

My XPS 8900 currently has: 

1. 8GB Dual Channel DDR4 2133MHz (4GBx2)

2. NVIDIA® GeForce® GT 730 2GB DDR3 

3. 1TB 7200 rpm Hard Drive

4. Integrated 7.1 with WAVE MAXXAudio Pro

5. 6th Generation Intel® Core™ i5-6400 Processor (6M Cache, up to 3.3 GHz).

 

I think my power supply is 450w.   

My budget is within $400. What should I upgrade? Thank you for your help.
