Problems related to upgrading graphics cards

Because your CPU is 4600+, no matter how good the graphics card is, your CPU will have a bottleneck and can't play the performance of the graphics card.

Personally, I think HD3850 on the graphics card is enough, and the game performance is good enough. Buy 5 12MB memory if you want. The memory width of HD3850 is 256, and a 22-inch monitor is just right.

The public version is the standard graphics card given by ATI or NV, and the manufacturers are all designed and manufactured according to the graphics card company, which is more compatible with the materials used for work. Non-public version is optional changes made by the manufacturer according to the design given by the graphics card company, reducing some components that have no essential influence on the graphics card to reduce the cost, and some are changed to enhance the performance of the graphics card, but the price will be more expensive than the public version. The overseas version is a non-public version, and the graphics card has been overclocked by the manufacturer when it leaves the factory, and the memory is healthy.

Graphics cards are usually packaged when you buy them, and they are brand-new and not folded. Ask how long the replacement and warranty will last if there is any problem.
