Looking to upgrade cpu/gpu

[SullyIreland85]

Hello

I am looking to upgrade to Nvidia 40 series graphics card from an RTX 3070 and I am wondering if it is possible

Will also PSU etc.

I currently have a Amd Ryzen 7 3700x HP OMEN 25L Desktop GT12-0475nd PC,

The motherboard is a HP 87c3.

Would the motherboard support PCIe Gen 5 ?? Or would I have to get a new motherboard aswell ?

I am not majorly tech savvy.

Any help would be much appreciated.

Hi @SullyIreland85 

Welcome to the HP Forum.

The RTX 3070 is a very good graphics card. This card pairs well with your case, power supply, and CPU.

A RTX 4070 would give you about 3080 performance. I don't think you can do a 4080 or higher given case constraints and power supply proximity to the graphics card.

I haven't seen any SFF RTX 4070s. A typical dual fan 2.5 inch slot 4070 would probably not work with your case and power supply location. This graphics card would be very close to the PSU if it fits in the case.

Your MB can handle a Ryzen 3900. I don't think this CPU upgrade would greatly enhance gaming.

The existing HP MB does not support PCIe 5.0 You could theoretically replace the HP uATX MB with a newer retail uATX MB having PCIe 5.0. But why? Nvidia 4000 series graphics cards run at PCIe 4.0.

Replacing the MB would: allow using newer and faster processors and NVME PCIe 5.0 SSDs where SSD performance improvements could only be detected by running benchmarks. Some PCIe 5.0 MBs cut the graphics card PCIe x16 slot to x8 when you install a PCIe 5.0 NVME drive in the PCIe 5.0 M.2 socket.

My guess is you would be looking at spending more than $1000.00 to upgrade:

The graphics card

The CPU

The MB and new RAM

The power supply

I would build or buy a new PC considering the upgrades you are looking to do.

Thank you so much for all the info Bill, very much appreciated. 

Everything you say makes perfect sense. 

I will look to buying a new PC in time I guess.

Thank ytou again.
