This is the third and final part of the February edition of build your own PC. We have taken a look at the PSU, case and CPU cooler as well as the CPU, RAM and motherboard in the two previous parts. This time we are deciding on a video card and the storage devices that we want to use in the computer.
Both components vary highly depending on the needs of the user building the PC. A gamer naturally wants a fast video card to play games, someone who collects photos or videos needs lots of storage and Office worker a quiet video card.
Build your own PC: Storage
Storage devices are hard drives and optical drives. Hard drives can be divided into the two categories Solid State Drives (SSD) and conventional hard drives.
There are basically two options for selecting hard drives:
Conventional hard drives have the advantage that they provide more storage for a cheaper price than Solid State Drives. Solid State Drives on the other hand are more expensive, offer way less storage but are way faster than convention drives. This is beneficial during system boot, playing games or loading applications.
The PC budget plays a big role in deciding the storage components. A good reliable Solid State Drive sells for about $250 for 64 Gigabytes of storage. Good conventional hard drives provide more than ten times the storage for that price.
PC users with a budget of about $400 for hard drives can consider combining Solid State Drives and conventional hard drives. The SSD would be used for the operating system and important applications (or games) whereas the standard hard drive would be used for storage.
Users with a lower budget should concentrate on buying a good fast hard drive instead that will be used for all files and the operating system.
When buying a Solid State Drive buyers need to make sure that it supports TRIM and garbage collection either out of the box or with a firmware update. TRIM and garbage collection ensure that the performance of the drive does not drop over time. This was a huge problem with first generation SSDs.
Hard drives come with speeds of 5400 and 7200. The former are more quiet while the latter are faster. A user who only works with light applications could consider buying a 5400 rpm drive whereas gamers or users with high end applications should buy a 7200 rpm drive.
The best combination at this point in time is to use a SSD as the boot drive and a 5400 rpm hard drive for storage.
The Intel X25-M is one of the fastest SSD when it comes to read speeds. The write speeds are usually lower in benchmarks but better in real life situations. It also offers 80 Gigabytes instead of 64 Gigabytes that most SSDs offer in that price range. It supports both TRIM and garbage collection.
The Samsung EcoGreen F3 is a drive with a speed of 5400. It has slower access and read speeds but offers 2 Terabytes of storage space. It is used to store everything but the most important applications, games and the operating system.
Build your own PC: Video Card
Selecting the right video cards usually depend on the level of gaming activity on the PC. We currently would suggest to buy an Ati Radeon 5000er video card as it is the only video card series currently supporting DirectX 11.
Gamers need to look at the Radeon 5850 or 5870 video cards for optimal performance. The selection here again depends on the budget. The Radeon 5870 retails for about $400, the 5850 for about $300. The 5870 is the faster card of the two and manages to beat the 5750 by 10fps+ in all benchmarks. Both cards can be used to play all modern games just fine.
Casual gamers might want to take a look at the ATI Radeon 5770 video card instead which retails for about $180.
