It is also worth searching for i5-2400, i5-2500, and i5-3470 based PCs on eBay, all very similar in performance

  1. UPDATE – Minor correction… I call this machine a i5-2400, which is what I thought I took off the shelf. Turns out this is a i5-3450. No real difference in terms of the PC, other than 1 gen newer and about 8% faster in performance than the i5-2400.

    NOTE – I will be comparing this in a future video soon to the i3-8100, Ryzen 3 1200, and the old, but new again Athlon X4 950. Be sure to watch for that video!

    NOTE 2 – This is the first video I've recorded with my new overhead microphone, notice I don't have a mic on my shirt for the first time. The audio isn't great, still working on how to set that up perfectly, but hopefully this isn't too bad. 🙂

  2. I sold my beast system, been on a mission to build a modest gaming PC using very little money and working on peoples PC's for parts, got $130NZD in it, i7 3770k @4.5Ghz, 16Gb Ripjaws 1600mhz, 1.5Tb HDD, 256Gb SSD, GTX 970 +250 mem clock, +150 core clock OC, Cooler Master Cooler, Cooler Master Gold Cert PSU, Cheap Office case (done on purpose to look crap lol) Gigabyte Z77X mobo. Runs everything I wanna play in 4K still, League of Legends gets 110FPS Maxed in 4k, everything else I wanna play runs mint in 4k too, my old system was a 6700k water cooled, GTX 1080, 16Gb ddr4, 256Gb ssd, 2x 3Gb hdd, EVGA 650w PSU, ROG mobo. I can honestly say to anyone looking to downgrade to do it if you think you don't need that power, there is nothing my new (old) system can't do that I need it to do, but to be fair I do most of my gaming on my Xbox One X in 4k (Don't hate me lol). good luck to everyone out there having fun with their PC's, Great Vid by the way, SUBSCRIBED!!

  3. i just got a 790 model with an i5 3.1Ghz +4GB for $93 shipped, and yea im putting a full size 1070 in it and yeah im actually going to downgrade the CPU to a 35watt i3 and dedicate it to mining. im cutting out the hard drive bays and metal behind the front grill to fit one large fan, or would 2x 120mm fans fit in the front?

  4. Hi,

    Here is my Computer Specs. I am planing to get a GTX 1050/1050Ti. Would it run ok? TIA.

    Motherboard: MSI H61M-P23 B3
    CPU: i3-3220 3.30 GHz
    RAM: 8GB DDR3 1600
    OS: Win 7 x64

  5. will a founders edition card fit in the system you are using and does it support ddr4 memory? pls answer

  6. I've got an i7 3770, 16GB ddr3 Crusial and Samsung memory, Samsung EVO 500gb SSD and GTX 1060 OC edition Asus. All in a Dell OptiPlex 7010. But the graphics card fit too! although to do that, i had to break a piece off from the slot support piece. OH, and i had an i5 2400 one before my new I7 3770 i just picked up last night! the I5, not bad at all @3.1GHZ and 3.4GHZ boost. I7 3770 = 3.4GHZ base and 3.9GHZ boost. That's why i bought it.

  7. ik im late but is buying a prebuilt and getting a gpu and psu to. or should i just buy parts sepratlly. my budget is around 250

  8. Every biuld I have done I have always had to update the bio on the old motherboard. For it to recognize the new gpu card no one ever tells people that why?

  9. 400 dollars on a 1070….
    200 dollars on a 1050 ti now… oh the good old pre bitcoin days

  10. i cant fvcking stop looking on your teeth in all your videos

  11. I installed a 1070 and now my tower won’t power on, my psu is only 500w should I buy a new one with 600+??

  12. Hi TechDeals… Good Job for all of your videos i really appreciate it and i already subscribe to your channel already. Can you help me with a little bit problem I have a G41M-P28 MSI motherboard and i wanted to play E-SPORTS such as dota 2,league of legends counter strike and i wanted to play gta too. I already have a Seagate 500 gb hdd. Can you help me what graphics card and monitor should i buy and can my G41 chipset handle such games like dota 2?

  13.

  14. let's say that my pc had 4GB of ram ,then i put an additional 4 gb of ram .what will happen when i will switch on the pc and how will i know that the ram that i have added is currently working?
    pls give me a response quickly

  15. if you get a 1050 do you have to remove the power supply before installation ? (no new psu)

  16. My new msi 1070 gamex does NOT boot with Sandy Bridge 2500k!!! It needs Ivy bridge or newer. Flashing bios is to risky and issues reported! But a 1060 3gb works, strange -WTF??? So now i has to upgrade to complete new system. Wut Bullshit!

  17. Hey Tech Deals, I have a big question about that Optiplex 3010. I too have that model but both Crucial and the Dell website show the maximum ram configuration for this system is 8 gb. How have you installed 16 gb and is the performance in any way hindered? What are your thoughts on exceeding this recommendation to 32 gb? Thanks!

  18. Absolutely brilliant, and something I can definitely point friends and colleagues to when they ask about budget gaming. Thank you.

    P.S. I love the plush humming bird – genius.

  19. please i neeeed helppppp the i5 3570k ivy bridge works in the optiplex 790mt Tech Deals … please helppppp

  20. i got a 880 omen desktop pc, would it be ok if i put a dual fan gpu instead of a blower style since its a decent sized case and designed specfically for gaming

  21. Do you have to buy a GPU that matches your vram? For instance some gpus are listed as gtx 1060 mini ddr5. Can you still use this card with ddr3 ram?
