New PC! Need help, pls!

Hey there!

I have a MacBook Pro 13’ and Unreal 4 Engine is ok, until I add highres textures and meshes.
So im planning on getting my “old” Tower back on, only for Unreal 4 Engine.

The components are:
CPU: AMD FX-4100 Quad Core CPU 4x3,6 Ghz
RAM: 8GB XMS DDR3
Harddrive: 500GB SATA
Power: 750Watt Straight Power mit Kabelmanagement
Mainboard: Asus M5A78L Usb3
Graphic: ATI HD 6450 mit 2GB und 2mal HDMI

Would this fit to work smooth with unreal 4 engine?

Im planning to buy a new Graphic Card, but I dont have much money. Is there a model for ppl like me?

Thanks for helping me out guys! <3

It’s not going to be that much better, main issue is the GPU and the CPU which are both pretty low-end. Macbook isn’t that great in the first place so if you can upgrade the GPU on the tower maybe that’ll help.

Thanks! I read a lot in this forum and changed my mind to build up a new pc.

Parts I already got now:
ASUS M4A87TD EVO
AMD Sockel AM3 Phenom II X6 1055T 6 x 2,8 GHz (with Turbo Unlock 3,3 GHz)
Gigabyte GeForce GTX 660 2048MB

I think im going to buy a small (250 or 500GB like) SSD Harddrive and 2 x 8GB RAM

What do you think about this? Will it run better with this components?
Thanks for your help!

Best regards!

Yes, that’ll be much better
