Can/should I use my old GPU while waiting for the new one?

[lordzsolt]

I'm in the process of building myself a new Gaming PC, though none of the stores in my country have the GPU I want in stock. While I wait, can/should I use my old GPU or something bad might happen?

My Build:
Processor: i5-4690K
Motherboard: Asus Z97-K
New GPU: EVGA GTX 970 FTW
Old GPU: EVG GTX 460
PSU: Seasonic M12II-620 EVO Edition
Memory: Kingston HyperX BEAST 16GB (2x8GB).

PS: If there's any changes you'd recommend I make, feel free to add. Only the CPU and the MOBO are bought.

No, you will be fine. Gaming wise it will be miles ahead of Intel HD graphics.
