It will need a GPU upgrade otherwise it will barely play modern games on low or medium. Looking at the case I can tell you there's going to be little to no airflow, your computer is going to melt or shutdown all the time due to overheating if you added a GPU. Infact, will a dedicated GPU even fit in that case? Plus you'll need to get a new & better PSU because pre-built systems have terrible PSU's. Plus it will need an aftermarket CPU cooler.
i7's are not meant for gaming. Desktop i5's and i7's are exactly the same performance when gaming.
Most games use 2-4GB of RAM (without ANY multitasking whatsoever) and 4GB WILL suffice although I recommend it least 6GB preferably 8gb so that you have some lee-way.
64 bit is better, it allows you to utilize more RAM etc.
You'd need it least a GTX 570 in order to play games on max settings smoothly. 8GB wouldn't really do anything.
At a $650 budget (im guessing your budget is that) you will NOT be able to find a pre-built system that can play games on max settings unless you build one yourself and overclock all the time. Even $1000+ pre-built systems always include crap GPU or crap something.
The computer is completly unsutible for gaming. The case is a desktop form factor and only supports low profile graphics cards. The fastest low profile card I have found is a ATI 7750 which will play some games at lowish resolution (720p) it would struggle with any thing else.
Also the PSU is only rated at 240w and has no PCI-e power connectors.
This computer is a business workhorse and not a gaming PC in any way.
I just don't want to buy everything, try to put it all together, and end up frying or breaking something.
I mean, how much money is saved anyway when building a computer on your own ?
Trust me, I had the exact same worries. I built my first computer like a week ago and am loving it am not regretting building my own. I managed to cut myself, overuse thermal paste and almost seriously damaged my motherboard and despite that in the end it works fine and performs excellent. So even if you're a klutz like me you'll be able to build it without worries.
Building your own computer automatically allows you to save hundreds, WITH getting better parts. Then if you get things on sale, you're saving even more. I strongly recommend you build your own unless you're willing to spend it least $2000+ on a pre-built system and still having to get a better graphics card because like someone else pointed out pre-built systems always use crap GPU.
Prebuilt pcs usually have crap for PSU, motherboard etc because those aren't specs that are posted or that anyone looks at. Also prebuilts often have no expansion room because it costs more to add more pcie lanes etc.
Building a computer is easy, just follow the directions(and use a antistatic wrist band)
but for the person that's just really adamant about buying a pre-built computer, how can you tell if the motherboard is inferior or just alright or actually pretty good ?
same goes for the computer case ?
Google the model number and write review next to it. If you're not planning to overclock, then there's no reason to do it - all motherboards will work and there aren't any advantages getting one board over another (except if one has more USB ports, for example). Getting H61 or B75 board would be all you'd need then. However, if you're going to overclock, then you should look at Z77 boards and read its review before buying it. Tom's Hardware has an excellent article on that:
You can buy computers built from some one else for a better price then what NewEgg( pre built) sells. Falcon Northwest for high end expensive comps with great customer service or a company like CyperPower that makes good computers where you can choose what parts you want and it will cost you about 10-20% higher then build it yourself. Prices will vary so it depends.
You have to add in shipping costs of the parts on building your own plus the cost of Windows. Best thing is check out a place like Cyper Power, have a budget. Configure a computer see what it costs then take all all those parts and price them individually and then add it up and see how much cheaper it is to build your own or have somebody else do it. Also, local computer shops are usually cheap too so call around. A local shop might build you one cheaper then an online place.
For the 650.00 you plan on spending for a pre built, you can build yourself a pretty decent computer.
