PC hardware update, little boost!

Two years having bought my PC, now I’m gone in search of components to update him.


Further to my misadventure with the graphics board, it seemed “obvious” to change it (as far as it also began to get nowhere fast with the recent games).

In the case of a graphics board, of course, it’s again necessary to know what we want to do with it: it’s going to determine the GPU which we are going to choose (Graphic Processor Unit), the range of the card (entry, middle or top of the range) and possibly other modifications to be brought.

My criteria were the following ones:

  • “Contained” Electric Consumption (because we are a little bit ecoresponsible on edges and that savings on an often switched on PC are not unimportant.
  • Performances little above the middle of the range (to hold a few years).
  • Stereoscopic 3D.
  • High quality manufacturer (with two bad adventures of premature overheating of the GPU on two “low-cost” cards… Won’t try a third).
  • Support of DirectX 11 (technology of Microsoft display on PC).


For the common of the users of PC, there are 2 brands of GPU: AMD and NVidia. In term of performances, the families of GPU of 2011 equal about (HD 6xxx side AMD and GTX5xx side NVidia), after a small bad patch on the previous NVidia series. Cards with GPU NVidia tend to be a little more expensive, to consume a little more, but they have some features covering specific needs (in particular for the Stereoscopic 3D).

It is necessary to know that side NVidia, it “is enough” to find a screen 120 Hz compatible, to have glasses 3DVision and it left. Concerning AMD… It is necessary to find compatible screens, to buy an additional driver, to have the compatible glasses… It is a little more complex thus more subject to headache and problems :-/

Furthermore, a few months before, NVidia brought out a GPU interesting enough, the GTX 560 Ti (for Titanium 😉 ), a processor of architecture Fermi overclocked by card manufacturer, having a contained heating and electric consumption and very good 3D performances (and being enough for the Stereoscopic 3D on a “classic” screen of 23 inches, which will come later).

My choice goes to ASUS (I always had good stories of their hardware), because not only they propose good graphics cards, but also good 3D screens, good Blu-ray readers for PC, etc. Furthermore, their card embarking the GTX 560 Ti is equipped with a special cooling system, called Direct CU. The latter is efficient and silent (according to the tests supplied by various sites). In brief, this card made eyes at me 🙂

An element stays to be taken into account… The power supply… This generation of NVidia (and AMD) cards needs two plugs of power supplies and consumes a little more… My PC initial power supply was a little bit just in connections and especially in power (thus brought warm/to slam because of its “quality”), it is necessary to think of replacing it by a at last 80+ certified power supply (fewer decreases of energy and less risk of burning out!).

The certification represents the power supply efficiency, and thus the quality of the tensions / currents which it can supply (80 + representing one protected from stability until 80 % of load with regard to the rated output indicated by the power supply: for example a power supply 500W certified 80 + must be capable of supplying 400W without stumbling).

I thus read lot of tests of power supply having at least on one year old (to find a good power supply which showed its ability and with which the price fell 😉 ) and there I choose a quality manufacturer, Corsair, for a 650W power supply (better value for money at the time of the purchase) silent and supplied well with cables for the installation (and a 7 year guaranty):

It only remain than to take up the whole in the tower (having dusted it of course, let us not forget that we cannot open the case not to blow up the guarantee). It’s not done alone, of course… Especially when the documentation of the mother board of the PC is non-existent :-/ Well… Just search with luck…

Well, the hypermarket PC case being what they are (the heat taking up and the power supply being situated on the top, it gets back this heat what tends to decrease its performances and its life expectancy… On quality cases, the power supply is below, logicaly), it is also desirable to strengthen ventilators to limit the risks of overheating (I would only say a thing, Noctua 😉 ), but that’s another adventure 😉



Here I am with an honorable PC with strong performances, with a restarted graphics card for at least two years and a power supply which will continue its career in the next tower, especially when the fashion of moment (and I hope on the long term) is in the reduction of energy consumption of components!


For games, it’s like night and day: made more fluid and more beautiful, with the possibility of rising in resolution 🙂
