yes,and I already learned that thing the hard way in the past
I'll concentrate on the psu and the VGA.
and yes psu,very important if you want the system to last.
OK , this is what I got:
3.1 GHz - i3-2100 3M/LGA1155 $120.00
Kingston DDR3 -1333 4GB $23.00
ECS H61H2-M3 V1.0 B3 $65.00
Foxconn TSAA725 ATX Case 400W $56.00
WD 500GB 7200RPM S-ATA II $88.00
Sony 24X DVDRW - Dual Layer Black SATA $23.00
Gigabyte GV-N550OC-1GI GeForce GTX 550Ti 1GB DDR5 $146.00
All of these stuff come to a total of $521.00
The VAT is the price * 1.1 which will give you $573.10
If you also add 10$ for shipping it will give you exactly $583.10 (874,650 LBP)
If you have any comments please post them and I will modify the specs according to it.

This is perfect but you have to reduce power it match the $400 (VAT included Im guessing)
the CPU to 2.6 GHz - G620 3M/LGA1155 $66.00

Also the Graphics have change to Gigabyte GV-N520TC-1GI Geforce GT520 up to 1GB DDR5 Dual w/TV $58.00 (not sure if this is compatible)

And if you have already a DVDRW, thats $23 off
sum is equal to 356, plus VAT = $391.6 and add $10 shipping $401.6
Downgrading the CPU is not an option, because that will cause a bottleneck and massive decrees in performance.
The 400W PSU should run it , but just to be safe it should be upgraded to at least 550W
Based on my experience downgrading the CPU will only bottleneck 5% to 10% which is barely noticeable. You will probably lose 2 to 3 frames per second in games by downgrading from 3.1ghz to 2.6ghz.
I say go for it, just to reduce the price.
Core 2 Duo <3.0 will give you a lot of stuttering and as explained bottleneck issues with all these modern games

Dual core CPU's are not ment for gaming, they are used for word procesing , web browsing and everyday computer stuff. I say stick with the i3 and upgrade the PSU.
A dual core is fine for games (g620 is a sandy bridge) and the power supply is good for the configuration. try getting a lower capacity HD to save some bucks.

I was not arguing if a Dual core is good for gaming or not. I was discussing the Bottleneck assumption you mentioned, which is totally over exaggerated by the way.
I have worked with many computers and I have tested Bottlenecks. Trust me its not like how they describe it in PC articles around the web

The i3 has 2 cores and is a direct replacement of the Core 2 Duo series. So i think that makes it a Dual core processor.


IMO the G620 will run games fine, not as good as an i3 though.
omar_killer did your uncle increase the price range,
Use some marketing techniques; tell him if he wants the PC to last at least 5 years, he has to invest at least $200 more. This would in turn pay out when his kids grow up and are in College/High school, where PCs now are required.

Also tell him later they would want to join Lebgeeks, and they would have been shunned if they didn't have a decent computer and no girls would want to chat with them cause their computer crashed while typing a/s/l. then they would need lots of therapy which would cost thousands of dollars. hence whats $200 for investing in their future. ;P
I just looked at a comparison between the two processors , it seems that the G850 is pretty good and very close to the 2100
That is the Core i3 2100T. The low power version of the Core i3 2100. Although it is pretty much the same architecture. What you want to check for in the comparison is clockspeeds, number of threads, and cache size (in decreasing order of importance). And no, I don't think either will bottleneck anything below a GTX 560 / 570.
@Gamer: yes that's great. Just looking at the specs sheets, one could see there's not much difference. Even benchmarks should show proportional scaling with frequency at most. The Pentium is only 16.13% slower in frequency.

For me, this is the same as the rest of Intel's pricing. In November 2008, when the Core i7's were released, the 920 (2.66GHz) was priced at $300, and the 940 (2.93GHz) at $600! After the 920, 940, and 965 went EoL, they were replaced by the 930, 950, and 975. Recently, the 960's price was $300. So huge profit margins it seems.
Actually me and my friend are planning on building a new computer rig with high end spec when we noticed an X79 motherboard with LGA 2011, and discovered the IVY Bridge chip set which began production and would be on available for purchase in April 2012, long story short we will be delaying building the rig Until April May.

http://en.wikipedia.org/wiki/Ivy_Bridge_%28microarchitecture%29
What type of system are you planning to build? (Please don't tell me single card + X79)
when you say single card, do you mean Graphics
and Im Not certain about the X79 cause till the Ivy Bridge Arrives I do not know what motherboard would be available,

I am looking into the cost/benefit of having an SLI to having a high end graphics.
Please don't go off-topic guys.
