Dell Inspiron 620 Upgrade Advice.


Oct 25, 2013
Hey there.

I've really been given a Dell Inspiron 620 and I am interested to know what I would be best upgrading, etc. This is the desktop tower version, not the slim thing.

I primarily surf the web, play a lot of games and do some photoshop work. Ideally I think I need to double the memory, add a new graphics card and perhaps get a new processor?

I'd like a GFX card which could handle some of the biggest games of last year decently. I don't expect to be able to play on Ultra Settings with +++AA, etc. Something that could maybe handle Simcity and Tomb Raider (2013) pretty well. Perhaps I'm best off with a nVidia card?

I'm no expert, so I'll leave it down to the trusted advice of you guys.

My budget for this is about £500-£600. I'd like to get the best I can for my budget, and at least grab a new graphics card and more RAM.

Will I need a BIOS update too?

Anything else you can reccomend I upgrade?

I'm not sure what the motherboard is
System Manufacturer: Dell Inc.

Thanks in advance!



The Inspiron 620 is a good and reliable system, but will be somewhat limited in performance, and value- perhaps £250, so I would suggest not overspending on moderate improvements.

You can use >

CPU > Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623I52500K

> which is a very good CPU from the 2nd generation. The thing is, your current CPU is 3.0GHz (3.3GHz Turbo Boost) and to use the i5-2500 you'd have to find a used one. A quick look at eBay UK suggests this would cost in the neighborhood- sorry neighbourhood of £130.00. In my view, the 300-400MHz increase in speed is on the edge of not being worth the cost due to the other limitations.

The increase in RAM (a slots, 1333 speed) to the maximum of 8GB is worthwhile to be able to run multiple applications. You might check the current RAM configuration in the event it has 2 X 2GB modules in which case you would have to replace both. If it has 1 X 4GB, then you can add another 1 X 4. I'd suggest that the added RAM be the exact model number of the other one- look for RAM on ebay specifically listed as coming out of an Inspiron 620.

For a graphics card, perhaps a GTX 650 2GB, which can be about £60-100 depending on used or new, from the US (cheaper but higher post and import fees) or from the UK.

Depending on your ultimate use, and degree of fuss allowed, but if you need /expect quite high performance, especially in gaming, you may be better off selling the Inspiron 620 and adding the £500 to have something already with a faster CPU (such as i7-3770), more RAM at a higher speed (such as 1600), and fast graphics card. One disadvantage of the i5 is that it is not hyperthreading- which is an advantage in programmes such as Photoshop. Have a look at >

> which is a completed listing for an Dell XPS, with an i7-3770, 8GB RAM, 2TB HD, and Radeon 7770 (1GB) card. The video card in this example is nothing special, but the system at £475 means you could look for a good GTX 650 (or 650ti) 2GB and something like this should be a good all-rounder and be useful for years longer.

Of course, it is less fuss to add some RAM and a better video card to the Inspiron, but to avoid overspending I would not change the CPU.

You do not need a new CPU at all. That i5 will max all modern games.I have an i5 2310 (worse than yours) and I can max all the games I play without any problems.

Simple do this: get a new 500w PSU from Antec, XFX, Corsair, Seasonic

Get 8gb RAM kit. (1.5v, cl9, 1600mhz)

Get a GPU with all the left over money. Something like an r9 270x or a gtx760.

I agree there is no point to upgrade the CPU for a tiny gain this person will not even be able to see. Leave the CPU alone.

A 2gb gtx650 is a terrible idea. Even a 650ti BOOST isn't powerful enough to use 2gb Vram. Get a more powerful card if you want to play games. I used a gtx650 when I RMA'd my 660ti and it could barely play skryin at low at 60fps. For a build designed around good gaming, you REALLY want a better GPU like the ones I listed.

Thanks for the input guys.

I have been doing a little research of my own, and will the components listed below not only be compatible with one another, but will they also fit in the case and not over-heat?

Graphics Card: EVGA GeForce GTX 770 4GB Dual Classified w/ EVGA ACX Cooler
HDD: Western Digital 1TB internal Hard Drive - Caviar Blue (3.5 inch)
Memory: Corsair CMZ8GX3M2A1600C9 Vengeance 8GB (2x4GB) DDR3 1600 Mhz CL9 XMP Performance
PSU: Corsair Builder Series CXM 600W Modular 80 PLUS Bronze Certified ATX/EPS

Thanks again!
