Upgrade GPU on Omni 220 PC

[Pratesh34349393]

Hi there, 

I have an HP Omni-1148hk PC, with the AMD Radeon HD 6450 GPU. This GPU has 1GB of VRAM.

I understand that there are very limited options for upgrading GPU on this PC. The ones listed on the official specs are below, but there would have been new GPUs made since then?

Would I notice much of a difference upgrading to one of the 2GB options? They are sometimes on Ebay at reasonable prices. 

Also, would this one work? https://www.ebay.co.uk/itm/Nvidia-GeForce-GTX-860M-4GB-MXM-CLEVO-EUROCOM/163667493917?hash=item261b5...

Graphics

Must select one of the following options:

• GeForce GT 520M MXM 3.0A (1 GB)
• GeForce GT 540M MXM 3.0A (2 GB)
• Radeon 6450A MXM 3.0A (1 GB)
• Radeon 6550A MXM 3.0A (2 GB)
• Radeon HD7450A MXM 3.0A (1 GB)
• Radeon HD7650A MXM 3.0A (2 GB)

@Pratesh34349393 , welcome to the forum.

The first thing that I want to point out is, HP has their motherboards made to their specifications.  They use their boards in many different models.  Even if a different model appears to have the same motherboard and specifications, this doesn't mean they are the exact same.  When HP lists video cards in their specifications it means that they have been fully tested to assure they are compatible with the motherboard they will be used in.  If the card is not on the list, it most likely won't be compatible.  The GTX 860M is not on the list.

Thanks for the reply Old_geekster.

I was wondering if the list provided by HP was created at the time the PC was released, and so maybe there were newer options that would also be compatible.

From the list provided by HP, do you think I would notice any positive difference from upgrading?

I presume the 2GB GPUS are better than the 1GB version I have? But would the difference be worth it or noticeable do you think?
