Hello everyone, I've bought a Fujitsu Esprimo P420 a while ago and it was modified to have a gygabite geforce gt 730 GPU. But I really do think it's finally a time for an upgrade. I am seriously considering the Asus Strix GTX 970. The thing that worries me is the motherboard and the power supply. It's almost obvious that I will have to buy a new power supply, but how do I know if the PSU is going to be compatible? Actually how can I know that the graphics card will fit in the case and suit the motherboard in the first place? If you have any information about the compatibility of the motherboard, which is D3230-A µATX with the GTX 970 and know which power supply will work fine please tell me. By the way some other specs are: CPU:Intel® Core i3-4160 CPU @ 3.60GHz RAM:8GB HDD:500GB Please help me because I'm pretty worried whether or not will I be able to upgrade to a better GPU and if you need more information feel free to ask.
