Hello guys,i own a Dell OptiPlex GX620 Tower model and i would like to upgrade my graphics card.I know it is a very old computer,but right now I don't have any budget for a new PC,and all I can afford is upgrading my graphics card.What gaming cards would i be able to install? I'm not really a hardcore gamer but i would like to play CoD:Black Ops,GTA IV etc.

Any suggestions?

P.S Sorry for my english,,it is not my native language.

The main thing we need to know if you have a slim tower or a full tower.

Either way you're looking at a $100 HD 7750 DDR5 as your best card. Probably won't be any recent games, since you're stuck with a Pentium 4 or Pentium D CPU. But anything before 2008 should play okay, and that graphics card will be plenty.

Definitely, here's a good one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102969

And you can save up some cash to build your own rig from scratch while you enjoy some older games (which are almost always less than $10 on Steam).

This is true that you cannot use anything serious, I mean video card, but it is related to what you can physically fit inside. You have Mini Tower, this is how it is called. Only a few 7750 can be actually installed, above mentioned Sapphire cannot! Next post will explain.
What processor you have now? Is it Pentium D or just Pentium? If you don't know, please install CPUID and run it, first tab will tell you the processor.
Also, how much memory you have now and which Win you have, XP, Vista or 7, is it 32 bit or 64 bit?
And finally what is your budget now?
Next post will deal with video card only.

THIS POST APPLICABLE TO MT (MINI TOWER) FORM FACTOR ONLY.

Unfortunately no card that is more than 7.5 inches long or 2 slots wide will PHYSICALLY FIT inside the case - it was found that only single bracket video card can fit due to BTX MOBO, where card internals facing upward towards PC internals, not ATX, where dual card design is blocking another PCI slot by facing downward.
If you prefer the card with beefier fan, then the length of the card must not exceed 7.5 inches, otherwise only "skinny" single bracket, single slot cards can physically fit.

Pictures below will prove my point.

View shows no room for dual bracket

Single bracket only, or you have to cut dual bracket in half

Here you can clearly see only single place for the bracket

Visual explanation

7.5 inches explained, also shown "obstacles"

05optiplex745singlebrac.jpg


This is the picture of actual "skinny" single slot video card (not sure which model)- perfect, "glove" fit.

06optiplex755mt3edit.jpg


So, I found 2 GDDR5 7750 cards and one DDR3 4GB (GDDR5 is better than GDDR3, even if GDD3 offers 2 GB RAM or more), which confirmed in reviews to fit Optiplex gx620, 745 and 755 cases (the difference between those models are different processors).

Skinny, flimsier in terms of construction, completely single slot XFX 7750 http://www.amazon.com/XFX-DisplayPort-PCI-Express-FX775AZNP4-FX-775A-ZNP4/dp/B007Z3T5JC

A bit beefier cooler, not as skinny, more durable in construction PowerColor AX7750 http://www.amazon.com/PowerColor-AX7750-1GBD5-DH-Video-Graphics/dp/B00775OC28/ref=sr_1_1?ie=UTF8&qid=1362783129&sr=8-1&keywords=AX7750+1GBD5-DH

There are a few 7770 cards which will fit here as well, but they would require power supply upgrade as well, and this is the pain in Optiplex GX620 due to different positions for mounting screws.

Please respond to my first post about memory, Win and processor, this is CPUID link http://www.cpuid.com/softwares/cpu-z.html

Kosovo? That sounds challenging for finding PC parts, how do you do that? Do you have a list of manufacturers available there, we can provide you with models, but it will be hm, not so easy to cover whole world.
Considering Kosovo, CPU upgrade is most likely out of question due to parts, as well as power supply.

Well you have already 2 options above, I will try to see other manufacturers, however it would be very helpful if you could check around to see which manufacturers are available. There are a lot of brands available in Europe and I know only one of them, however I seen many more brands, so if you can just provided brand names this would be great.

Come back tomorrow.

I also have this same computer in the slim model. It has an Intel Pentium 4 3.0 ghz processor with Intel 945G with 1 GB RAM. I was wondering if this graphics card would work.

Also, I can provide more system details if needed. I am using Ubuntu 13.10 64-Bit currently with Unity.

I have a Dell Optiplex GX620, a Pentium D 2.8, and 2gb ddr2 ram. I installed a Radeon HD5450 2gb overclocked the processing speed to 700mhz and memory to 635mhz, and installed a fan in front of the graphics card. The system will play Call of Duty 4, Borderlands 2, Torchlight 2, Garry's Mod, Civilization V on high settings, Minecraft on high settings. Age of Empires 3: Asian Dynasty, Left for Dead, etc ...
All these games play great with no lag and graphics card has not overheated at all.

I own an Optiplex GX620 MT(Mini Tower), Intel Pentium 4 - 3.0 Ghz, 4 GB RAM, 500 GB HDD, Win 7 Pro 64

I want to upgrade my video card to one that has an HDMI port and while I was at it I thought I'd spring for something in the $50 - $100 range with an admirable benchmark. Been hitting roadblocks finding a full height that fits the criteria til I found this post. Both linked cards are now unavailable. The "flimsier" one is now only available for $200 and the beefier one has been replaced by XFX with a card that is over the 7.5 inch threshold. Do you have any advice or links you can send my way? I just realized that these cards would also require a PSU upgrade. Well that is something I'd like to avoid, if possible. This is a toughie.

I run an HDMI cord from my computer to a RCVR that runs to my LCD TV and use it as my EVERYTHING monitor. I stream, I watch movies, I don't play many games seeing as my system doesn't have the power for it. That's what my 360 is for. Any help would be greatly appreciated. I'd like to find something by the end of the month. Later. Awesome post BTW.

please start a new thread for your question. makes it easier for people and they will be more likely to get involved if there is not already a bunch of replies on a thread from last year!!

repost your question and include the information on the power supply in it. mainly your looking at total watts and the amps on the 12 volt rail from the label. this info is what we need to be sure what you can and can not run.

thanks and we will be glad to help.

Fantastic. I don't know how you found those but am so happy you did. I think the 250 is the one I'll buy.

I cut the back of the pcie x1 slot off and can easily fit my 3870x2. It still lags on the menu of COD: black ops though, I would recommend doing any gaming what so ever with a gx620. Your best bet would be to get an optiplex 755 motherboard and upgrade to a core 2 duo (or quad)
