I simply looked at the reviews on the card on the computer listed and the reviews say that the card sucks. The memory isn't the only thing to look at. ;3
Alright, I'll give you a few words on graphics cards.
- It's good if it has at least one fan mounted on it. The case's fans will not keep the GPU (Graphics Processing Unit / Graphics Card) cool enough. If a card runs hot, there's a good chance it will break or performance will suffer.
- A good card has 1 GB+ of dedicated memory. This is, however, not the only thing to look at. The amount of cores and whatnot are also important. Instead of reading the amount of cores and trying to find how good it is, I advise looking at the reviews. If they say that it runs cool and runs games fairly fast, it's a good card. You can find reviews on lots of cards on Newegg.com
- There is a difference between on-board GPUs and external GPUs. Some computers will advertise that their cards are great, but if it's an onboard card, it will be lackluster in quality.
Sorry, I don't know a whole lot about computers, but that's what I have to say on graphics cards. Again, the one I use is the
MSI R6670 which is very cost effective if you're willing to invest a little bit of effort to add it to your computer. Otherwise, do as I said and research the card on whatever computer you will be getting. Your budget would get you far if you custom-build your computer, but with brand names, even a thousand bucks wont get you a great computer.
