System Comparison and Cost

This is just a quick overview of what parts are being utilized with each system, and how much each part cost. For grins, I am only going to provide the prices that I paid for my Q6600 system from back in 2007, or any upgraded parts along the way will also be the then price, while the new i7 system will be today’s prices. I also cannot find that I ordered a power supply, so my initial PSU must have been reused from an old build. I did eventually purchase a new one and will list it under the upgrade section.


Old PC  
Component Model Cost
Processor Intel Q6600 $279.99
Motherboard ASUS P5E  $229.99
Memory 2x Mushkin PC2 8500 2GB Kit  $199.98
Video Card EVGA 8800 GTX $549.99
Case Cooler Master Cosmos  $189.99
ROM Drive ASUS DVD-ROM  $20.99
Storage  Seagate 500GB 7200RPM HDD  $119.99
Initial Cost $1,590.92
Upgrade – Video Card  EVGA GTX 275 Superclocked  $269.99
Upgrade- Storage  OCZ Agility 2 60GB SSD  $119.99
Upgrade – Power Supply  OCZ ModXStream Pro 600w  $74.99
Upgrade – Video Card  EVGA GTX 570 Classified  $349.99
Upgrade – Storage  Samsung 840 Pro 128GB SSD  $139.76
PC Cost Total $2,545.64
 New PC  
Processor Intel i7 4770k $339.99
Motherboard  GIGABYTE Z87X-UD4H  $197.98
Memory  Corsair Vengeance Pro PC3-15000 16GB Kit  $150.46
Video Card  REUSED – EVGA GTX 570 Classified
Case  Fractal Design Define XL R2  $119.99
Storage  REUSED – Samsung 840 Pro 128GB SSD 
Power Supply  REUSED – OCZ ModXStream Pro 600w 
Total $808.42 


As you can see, my old system originally netted me a cost of $1590.92. Mind you, too, that the power supply was reused from a different system that I had, so that saved me a decent amount of money. I did a bunch of upgrades along the way, which also netted me an additional cost of $944.95. So overall, I spent $2535.87 on my Q6600 system! That’s a lot of money! In case you’re wondering, I also did not include the cost of the case that I worked with my system in for this review, as that was a case that I reviewed and I only recently transported my system over to it. That one is the Corsair Carbide Air 540, which is absolutely wonderful to work with. If you’re interested in picking up that case, you can grab it on Amazon for $139.99 shipped. I did include the cost of the new system’s case, the Fractal Design Define XL R2, as I needed a case to permanently install the components in.

Old System ASUS P5E With Q6600

The new system had a couple reused parts, so with that said, this system cost a total of $808.42 to put together. I did reuse one of the most expensive components in a PC, the video card, so if I were to upgrade that, I could probably figure roughly another $350-400, depending on what flavor video card I opt to go with again. Right now my GTX 570 seems to run most modern games to a level that I can accept, so I do not have plans on upgrading that.

New System With GIGABYTE Z87X-UD4H And 4770k

Should you include the cost of everything inside this system, the total cost to build would have cost a total of $1514.14. Not bad for a sweet system, in my opinion! What’s more interesting, though, is I’m right around the same ballpark of my original system’s cost.

The Test Setups

For my testing, I used the same video card, PSU, and SSD. I did remove the 500GB HDD, as that was only used for storage purposes and was irrelevant to my testing. I also ran Windows 7 Professional on both systems, as ASUS does not have any Windows 8 driver support for the P5E motherboard. All of these choices will make things easier to work with and will show you a more true representation of what a motherboard, memory, and CPU upgrade can do for you if you reused some old components.

If you scroll back up a bit, you can see the various components that I used in each setup.

Anyway, let’s get into the meat of this review and see how well the old Q6600 system pits against the i7 4770k system!
